24bfd19bb7 block, bfq: update blkio stats outside the scheduler lock 
bfq invokes various blkg_*stats_* functions to update the statistics
contained in the special files blkio.bfq.* in the blkio controller
groups, i.e., the I/O accounting related to the proportional-share
policy provided by bfq. The execution of these functions takes a
considerable percentage, about 40%, of the total per-request execution
time of bfq (i.e., of the sum of the execution time of all the bfq
functions that have to be executed to process an I/O request from its
creation to its destruction).  This reduces the request-processing
rate sustainable by bfq noticeably, even on a multicore CPU. In fact,
the bfq functions that invoke blkg_*stats_* functions cannot be
executed in parallel with the rest of the code of bfq, because both
are executed under the same same per-device scheduler lock.

To reduce this slowdown, this commit moves, wherever possible, the
invocation of these functions (more precisely, of the bfq functions
that invoke blkg_*stats_* functions) outside the critical sections
protected by the scheduler lock.

With this change, and with all blkio.bfq.* statistics enabled, the
throughput grows, e.g., from 250 to 310 KIOPS (+25%) on an Intel
i7-4850HQ, in case of 8 threads doing random I/O in parallel on
null_blk, with the latter configured with 0 latency. We obtained the
same or higher throughput boosts, up to +30%, with other processors
(some figures are reported in the documentation). For our tests, we
used the script [1], with which our results can be easily reproduced.

NOTE. This commit still protects the invocation of blkg_*stats_*
functions with the request_queue lock, because the group these
functions are invoked on may otherwise disappear before or while these
functions are executed.  Fortunately, tests without even this lock
show, by difference, that the serialization caused by this lock has a
little impact (at most ~5% of throughput reduction).

614822f81f block, bfq: add missing invocations of bfqg_stats_update_io_add/remove 
bfqg_stats_update_io_add and bfqg_stats_update_io_remove are to be
invoked, respectively, when an I/O request enters and when an I/O
request exits the scheduler. Unfortunately, bfq does not fully comply
with this scheme, because it does not invoke these functions for
requests that are inserted into or extracted from its priority
dispatch list. This commit fixes this mistake.

68017e5d87 doc, block, bfq: update max IOPS sustainable with BFQ 
We have investigated more deeply the performance of BFQ, in terms of
number of IOPS that can be processed by the CPU when BFQ is used as
I/O scheduler. In more detail, using the script [1], we have measured
the number of IOPS reached on top of a null block device configured
with zero latency, as a function of the workload (sequential read,
sequential write, random read, random write) and of the system (we
considered desktops, laptops and embedded systems).

Basing on the resulting figures, with this commit we update the
current, conservative IOPS range reported in BFQ documentation. In
particular, the documentation now reports, for each of three different
systems, the lowest number of IOPS obtained for that system with the
above test (namely, the value obtained with the workload leading to
the lowest IOPS).

4fc930896d ide: Make ide_cdrom_prep_fs() initialize the sense buffer pointer 
The changes introduced through commit 82ed4db499 assume that the
sense buffer pointer in struct scsi_request is initialized for all
requests - passthrough and filesystem requests. Hence make sure
that that pointer is initialized for filesystem requests. Remove
the memset() call that clears .cmd because the scsi_req_init()
call in ide_initialize_rq() already initializes the .cmd.

Fixes: commit 82ed4db499 ("block: split scsi_request out of struct request")

4e4510fec4 sound updates for 4.15-rc1 
There are no big surprising changes in this cycle, yet not too
 boring, either.  The biggest change from diffstat POV is the removal
 of the legacy OSS driver codes that have been already disabled for a
 long time.  This will bring a few trivial merge conflicts.
 
 As new features in ASoC side, there are two things: a new AC97 bus
 implementation and AMD Stony platform support.  Both include the
 relevant changes shared with other subsystems, e.g. AC97 MFD changes
 and DRM AMD changes.
 
 Some other highlighted topics are:
 - A bunch of USB-audio drivers got the hardening against the malicious
   device accesses with a new helper code for endpoint sanity check.
 - Lots of cleanups for ASoC Intel platform code, including support for
   their open source audio firmware.
 - Continued ASoC core componentization works.
 - Support for scaling MCLK with sample rate in ASoC simple-card.
 - Stabler PCM hot-unplug capability, especially for ASoC usages.

6aa2f9441f This is the bulk of GPIO changes for the v4.15 kernel cycle: 
CORE:
 - Fix the semantics of raw GPIO to actually be raw. No
   inversion semantics as before, but also no open draining,
   and allow the raw operations to affect lines used for
   interrupts as the caller supposedly knows what they are
   doing if they are getting the big hammer.
 
 - Rewrote the __inner_function() notation calls to names that
   make more sense. I just find this kind of code disturbing.
 
 - Drop the .irq_base() field from the gpiochip since now all
   IRQs are mapped dynamically. This is nice.
 
 - Support for .get_multiple() in the core driver API. This
   allows us to read several GPIO lines with a single
   register read. This has high value for some usecases: it
   can be used to create oscilloscopes and signal analyzers
   and other things that rely on reading several lines at
   exactly the same instant. Also a generally nice
   optimization. This uses the new assign_bit() macro from
   the bitops lib that was ACKed by Andrew Morton and
   is implemented for two drivers, one of them being the
   generic MMIO driver so everyone using that will be able
   to benefit from this.
 
 - Do not allow requests of Open Drain and Open Source
   setting of a GPIO line simultaneously. If the hardware
   actually supports enabling both at the same time the
   electrical result would be disastrous.
 
 - A new interrupt chip core helper. This will be helpful
   to deal with "banked" GPIOs, which means GPIO controllers
   with several logical blocks of GPIO inside them. This
   is several gpiochips per device in the device model, in
   contrast to the case when there is a 1-to-1 relationship
   between a device and a gpiochip.
 
 NEW DRIVERS:
 
 - Maxim MAX3191x industrial serializer, a very interesting
   piece of professional I/O hardware.
 
 - Uniphier GPIO driver. This is the GPIO block from the
   recent Socionext (ex Fujitsu and Panasonic) platform.
 
 - Tegra 186 driver. This is based on the new banked GPIO
   infrastructure.
 
 OTHER IMPROVEMENTS:
 
 - Some documentation improvements.
 
 - Wakeup support for the DesignWare DWAPB GPIO controller.
 
 - Reset line support on the DesignWare DWAPB GPIO controller.
 
 - Several non-critical bug fixes and improvements for the
   Broadcom BRCMSTB driver.
 
 - Misc non-critical bug fixes like exotic errorpaths, removal
   of dead code etc.
 
 - Explicit comments on fall-through switch() statements.

Merge tag 'gpio-v4.15-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.15 kernel cycle:

  Core:

   - Fix the semantics of raw GPIO to actually be raw. No inversion
     semantics as before, but also no open draining, and allow the raw
     operations to affect lines used for interrupts as the caller
     supposedly knows what they are doing if they are getting the big
     hammer.

   - Rewrote the __inner_function() notation calls to names that make
     more sense. I just find this kind of code disturbing.

   - Drop the .irq_base() field from the gpiochip since now all IRQs are
     mapped dynamically. This is nice.

   - Support for .get_multiple() in the core driver API. This allows us
     to read several GPIO lines with a single register read. This has
     high value for some usecases: it can be used to create
     oscilloscopes and signal analyzers and other things that rely on
     reading several lines at exactly the same instant. Also a generally
     nice optimization. This uses the new assign_bit() macro from the
     bitops lib that was ACKed by Andrew Morton and is implemented for
     two drivers, one of them being the generic MMIO driver so everyone
     using that will be able to benefit from this.

   - Do not allow requests of Open Drain and Open Source setting of a
     GPIO line simultaneously. If the hardware actually supports
     enabling both at the same time the electrical result would be
     disastrous.

   - A new interrupt chip core helper. This will be helpful to deal with
     "banked" GPIOs, which means GPIO controllers with several logical
     blocks of GPIO inside them. This is several gpiochips per device in
     the device model, in contrast to the case when there is a 1-to-1
     relationship between a device and a gpiochip.

  New drivers:

   - Maxim MAX3191x industrial serializer, a very interesting piece of
     professional I/O hardware.

   - Uniphier GPIO driver. This is the GPIO block from the recent
     Socionext (ex Fujitsu and Panasonic) platform.

   - Tegra 186 driver. This is based on the new banked GPIO
     infrastructure.

  Other improvements:

   - Some documentation improvements.

   - Wakeup support for the DesignWare DWAPB GPIO controller.

   - Reset line support on the DesignWare DWAPB GPIO controller.

   - Several non-critical bug fixes and improvements for the Broadcom
     BRCMSTB driver.

   - Misc non-critical bug fixes like exotic errorpaths, removal of dead
     code etc.

   - Explicit comments on fall-through switch() statements"

Pull core block layer updates from Jens Axboe:
 "This is the main pull request for block storage for 4.15-rc1.

  Nothing out of the ordinary in here, and no API changes or anything
  like that. Just various new features for drivers, core changes, etc.
  In particular, this pull request contains:

   - A patch series from Bart, closing the whole on blk/scsi-mq queue
     quescing.

   - A series from Christoph, building towards hidden gendisks (for
     multipath) and ability to move bio chains around.

   - NVMe
        - Support for native multipath for NVMe (Christoph).
        - Userspace notifications for AENs (Keith).
        - Command side-effects support (Keith).
        - SGL support (Chaitanya Kulkarni)
        - FC fixes and improvements (James Smart)
        - Lots of fixes and tweaks (Various)

   - bcache
        - New maintainer (Michael Lyle)
        - Writeback control improvements (Michael)
        - Various fixes (Coly, Elena, Eric, Liang, et al)

   - lightnvm updates, mostly centered around the pblk interface
     (Javier, Hans, and Rakesh).

   - Removal of unused bio/bvec kmap atomic interfaces (me, Christoph)

   - Writeback series that fix the much discussed hundreds of millions
     of sync-all units. This goes all the way, as discussed previously
     (me).

   - Fix for missing wakeup on writeback timer adjustments (Yafang
     Shao).

   - Fix laptop mode on blk-mq (me).

   - {mq,name} tupple lookup for IO schedulers, allowing us to have
     alias names. This means you can use 'deadline' on both !mq and on
     mq (where it's called mq-deadline). (me).

   - blktrace race fix, oopsing on sg load (me).

   - blk-mq optimizations (me).

   - Obscure waitqueue race fix for kyber (Omar).

   - NBD fixes (Josef).

   - Disable writeback throttling by default on bfq, like we do on cfq
     (Luca Miccio).

   - Series from Ming that enable us to treat flush requests on blk-mq
     like any other request. This is a really nice cleanup.

   - Series from Ming that improves merging on blk-mq with schedulers,
     getting us closer to flipping the switch on scsi-mq again.

   - BFQ updates (Paolo).

   - blk-mq atomic flags memory ordering fixes (Peter Z).

   - Loop cgroup support (Shaohua).

   - Lots of minor fixes from lots of different folks, both for core and
     driver code"

29309a4eb8 We've got a total of 17 GFS2 patches for this merge window. The 
patches are basically in three categories: (1) patches related to
 broken xfstest cases, (2) patches related to improving iomap and
 start using it in GFS2, and (3) general typos and clarifications.
 
 Please note that one of the iomap patches extends beyond GFS2 and
 affects other file systems, but it was publically reviewed by a
 variety of file system people in the community.
 
 1. Andreas has a patch that simply renames variable 'bsize' to 'factor'
    to clarify the logic related to gfs2_block_map.
 2. He also has a patch to correctly set ctime in the setflags ioctl,
    which fixes broken xfstests test 277.
 3. He also fixed broken xfstest 258, due to an atime initialization
    problem.
 4. He also fixed broken xfstest 307, in which GFS2 was not setting
    ctime when setting acls.
 5. He has a patch to switch general iomap code from blkno to disk
    offset for a variety of file systems.
 6. He has a patch to add a new IOMAP_F_DATA_INLINE flag for iomap
    to indicate blocks that have data mixed with metadata.
 7. I contributed a patch to make inode height info part of the
    'metapath' data structure to facilitate using iomap in GFS2.
 8. I have a patch to start using iomap inside GFS2 and switch GFS2's
    block_map functions to use iomap under the covers.
 9. I have a patch to switch GFS2's fiemap implementation from using
    block_map to using iomap under the covers.
 10. Andreas has a patch to implement SEEK_HOLE and SEEK_DATA via
     iomap in GFS2.
 11. I have a patch related to journaled data pages not being properly
     synced to media when writing inodes. This was caught with xfstests.
 12. I have a patch to fix another failing xfstest case in which
     switching a file from ordered_write to journaled data via set_flags
     caused a deadlock.
 13. Andreas has a patch to fix failing xfstest case 066, which was
     due to not properly syncing dirty inodes when changing extended
     attributes.
 14. Andreas fixed a minor typo in a comment.
 15. Andreas contributed a patch to partially fix xfstest 424, which
     involved GET_FLAGS and SET_FLAGS ioctl. This is also a cleanup
     and simplification of the translation of flags from fs flags to
     gfs2 flags.
 16. He also added support for STATX_ATTR_ in statx, which fixed broken
     xfstest 424.
 17. He also contributed a fix for failing xfstest 093 which fixes a
     recursive glock problem with gfs2_xattr_get and _set.

Pull btrfs updates from David Sterba:
 "There are some new user features and the usual load of invisible
  enhancements or cleanups.

  New features:

   - extend mount options to specify zlib compression level, -o
     compress=zlib:9

   - v2 of ioctl "extent to inode mapping", addressing a usecase where
     we want to retrieve more but inaccurate results and do the
     postprocessing in userspace, aiding defragmentation or
     deduplication tools

   - populate compression heuristics logic, do data sampling and try to
     guess compressibility by: looking for repeated patterns, counting
     unique byte values and distribution, calculating Shannon entropy;
     this will need more benchmarking and possibly fine tuning, but the
     base should be good enough

   - enable indexing for btrfs as lower filesystem in overlayfs

   - speedup page cache readahead during send on large files

  Internal enhancements:

   - more sanity checks of b-tree items when reading them from disk

   - more EINVAL/EUCLEAN fixups, missing BLK_STS_* conversion, other
     errno or error handling fixes

   - remove some homegrown IO-related logic, that's been obsoleted by
     core block layer changes (batching, plug/unplug, own counters)

   - add ref-verify, optional debugging feature to verify extent
     reference accounting

   - simplify code handling outstanding extents, make it more clear
     where and how the accounting is done

   - make delalloc reservations per-inode, simplify the code and make
     the logic more straightforward

   - extensive cleanup of delayed refs code

  Notable fixes:

   - fix send ioctl on 32bit with 64bit kernel"

808eb24e0e New in this version: 
- Refactor the incore extent map manipulations to use a cursor instead of
   directly modifying extent data.
 - Refactor the incore extent map cursor to use an in-memory btree instead
   of a single high-order allocation.  This eliminates a major source of
   complaints about insufficient memory when opening a heavily fragmented
   file into a system whose memory is also heavily fragmented.
 - Fix a longstanding bug where deleting a file with a complex extended
   attribute btree incorrectly handled memory pointers, which could lead
   to memory corruption.
 - Improve metadata validation to eliminate crashing problems found while
   fuzzing xfs.
 - Move the error injection tag definitions into libxfs to be shared with
   userspace components.
 - Fix some log recovery bugs where we'd underflow log block position
   vector and incorrectly fail log recovery.
 - Drain the buffer lru after log recovery to force recovered buffers back
   through the verifiers after mount.  On a v4 filesystem the log never
   attaches verifiers during log replay (v5 does), so we could end up with
   buffers marked verified but without having ever been verified.
 - Fix various other bugs.
 - Introduce the first part of a new online fsck tool.  The new fsck tool
   will be able to iterate every piece of metadata in the filesystem to
   look for obvious errors and corruptions.  In the next release cycle
   the checking will be extended to cross-reference with the other fs
   metadata, so this feature should only be used by the developers in the
   mean time.

Merge tag 'xfs-4.15-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs updates from Darrick Wong:
 "xfs: great scads of new stuff for 4.15.

  This merge cycle, we're making some substantive changes to XFS. The
  in-core extent mappings have been refactored to use proper iterators
  and a btree to handle heavily fragmented files without needing
  high-order memory allocations; some important log recovery bug fixes;
  and the first part of the online fsck functionality.

  (The online fsck feature is disabled by default and more pieces of it
  will be coming in future release cycles.)

  This giant pile of patches has been run through a full xfstests run
  over the weekend and through a quick xfstests run against this
  morning's master, with no major failures reported.

  New in this version:

   - Refactor the incore extent map manipulations to use a cursor
     instead of directly modifying extent data.

   - Refactor the incore extent map cursor to use an in-memory btree
     instead of a single high-order allocation. This eliminates a major

449fcf3ab0 Staging/IIO patches for 4.15-rc1 
Here is the "big" staging and IIO driver update for 4.15-rc1.
 
 Lots and lots of little changes, almost all minor code cleanups as the
 Outreachy application process happened during this development cycle.
 Also happened was a lot of IIO driver activity, and the typec USB code
 moving out of staging to drivers/usb (same commits are in the USB tree
 on a persistent branch to not cause merge issues.)
 
 Overall, it's a wash, I think we added a few hundred more lines than
 removed, but really only a few thousand were modified at all.
 
 All of these have been in linux-next for a while.  There might be a
 merge issue with Al's vfs tree in the pi433 driver (take his changes,
 they are always better), and the media tree with some of the odd atomisp
 cleanups (take the media tree's version).
