xdp: Fix type of string pointer in __XDP_ACT_SYM_TAB
The table entry in __XDP_ACT_SYM_TAB for the last item is set
to { -1, 0 } where it should be { -1, NULL } as the second item
is a pointer to a string.
Fixes the following sparse warnings:
./include/trace/events/xdp.h:28:1: warning: Using plain integer as NULL pointer

"This continues with work on code refactoring, sanity checks and space
handling. There are some less user visible changes, nothing that would
particularly stand out.
User visible changes:
- tree checker, more sanity checks of:
- ROOT_ITEM (key, size, generation, level, alignment, flags)
- EXTENT_ITEM and METADATA_ITEM checks (key, size, offset,
alignment, refs)
- tree block reference items
- EXTENT_DATA_REF (key, hash, offset)
- deprecate flag BTRFS_SUBVOL_CREATE_ASYNC for subvolume creation
ioctl, scheduled removal in 5.7
- delete stale and unused UAPI definitions
BTRFS_DEV_REPLACE_ITEM_STATE_*
- improved export of debugging information available via existing
sysfs directory structure
- try harder to delete relations between qgroups and allow to delete
orphan entries
- remove unreliable space checks before relocation starts
Core:
- space handling:
- improved ticket reservations and other high level logic in
order to remove special cases
- factor flushing infrastructure and use it for different
contexts, allows to remove some special case handling
- reduce metadata reservation when only updating inodes
- reduce global block reserve minimum size (affects small
filesystems)
- improved overcommit logic wrt global block reserve
- tests:
- fix memory leaks in extent IO tree
- catch all TRIM range
Fixes:
- fix ENOSPC errors, leading to transaction aborts, when cloning
extents
- several fixes for inode number cache (mount option inode_cache)
- fix potential soft lockups during send when traversing large trees
- fix unaligned access to space cache pages with SLUB debug on
(PowerPC)
Other:
- refactoring public/private functions, moving to new or more
appropriate files
- defines converted to enums
- error handling improvements
- more assertions and comments
- old code deletion"

Staging/IIO driver patches for 5.4-rc1
Here is the big staging/iio driver update for 5.4-rc1.
Lots of churn here, with a few driver/filesystems moving out of staging
finally:
- erofs moved out of staging
- greybus core code moved out of staging
Along with that, a new filesytem has been added:
- extfat
to provide support for those devices requiring that filesystem (i.e.
transfer devices to/from windows systems or printers.)
Other than that, there a number of new IIO drivers, and lots and lots
and lots of staging driver cleanups and minor fixes as people continue
to dig into those for easy changes.
All of these have been in linux-next for a while with no reported
issues.

Power management updates for 5.4-rc1
- Rework the main suspend-to-idle control flow to avoid repeating
"noirq" device resume and suspend operations in case of spurious
wakeups from the ACPI EC and decouple the ACPI EC wakeups support
from the LPS0 _DSM support (Rafael Wysocki).
- Extend the wakeup sources framework to expose wakeup sources as
device objects in sysfs (Tri Vo, Stephen Boyd).
- Expose system suspend statistics in sysfs (Kalesh Singh).
- Introduce a new haltpoll cpuidle driver and a new matching
governor for virtualized guests wanting to do guest-side polling
in the idle loop (Marcelo Tosatti, Joao Martins, Wanpeng Li,
Stephen Rothwell).
- Fix the menu and teo cpuidle governors to allow the scheduler tick
to be stopped if PM QoS is used to limit the CPU idle state exit
latency in some cases (Rafael Wysocki).
- Increase the resolution of the play_idle() argument to microseconds
for more fine-grained injection of CPU idle cycles (Daniel Lezcano).
- Switch over some users of cpuidle notifiers to the new QoS-based
frequency limits and drop the CPUFREQ_ADJUST and CPUFREQ_NOTIFY
policy notifier events (Viresh Kumar).

blkcg: implement blk-iocost
This patchset implements IO cost model based work-conserving
proportional controller.
While io.latency provides the capability to comprehensively prioritize
and protect IOs depending on the cgroups, its protection is binary -
the lowest latency target cgroup which is suffering is protected at
the cost of all others. In many use cases including stacking multiple
workload containers in a single system, it's necessary to distribute
IO capacity with better granularity.
One challenge of controlling IO resources is the lack of trivially
observable cost metric. The most common metrics - bandwidth and iops
- can be off by orders of magnitude depending on the device type and
IO pattern. However, the cost isn't a complete mystery. Given
several key attributes, we can make fairly reliable predictions on how
expensive a given stream of IOs would be, at least compared to other
IO patterns.
The function which determines the cost of a given IO is the IO cost
model for the device. This controller distributes IO capacity based
on the costs estimated by such model. The more accurate the cost
model the better but the controller adapts based on IO completion
latency and as long as the relative costs across differents IO
patterns are consistent and sensible, it'll adapt to the actual
performance of the device.
Currently, the only implemented cost model is a simple linear one with
a few sets of default parameters for different classes of device.
This covers most common devices reasonably well. All the
infrastructure to tune and add different cost models is already in
place and a later patch will also allow using bpf progs for cost
models.
Please see the top comment in blk-iocost.c and documentation for
more details.

rxrpc: Use skb_unshare() rather than skb_cow_data()
The in-place decryption routines in AF_RXRPC's rxkad security module
currently call skb_cow_data() to make sure the data isn't shared and that
the skb can be written over. This has a problem, however, as the softirq
handler may be still holding a ref or the Rx ring may be holding multiple
refs when skb_cow_data() is called in rxkad_verify_packet() - and so
skb_shared() returns true and __pskb_pull_tail() dislikes that. If this
occurs, something like the following report will be generated.

Fix this by using skb_unshare() instead in the input path for DATA packets

rxrpc: Use the tx-phase skb flag to simplify tracing
Use the previously-added transmit-phase skbuff private flag to simplify the socket buffer tracing a bit. Which phase the skbuff comes from can now be divined from the skb rather than having to be guessed from the call state. We can also reduce the number of rxrpc_skb_trace values by eliminating the difference between Tx and Rx in the symbols. Signed-off-by: David Howells <dhowells@redhat.com> |

erofs: move erofs out of staging
EROFS filesystem has been merged into linux-staging for a year. EROFS is designed to be a better solution of saving extra storage space with guaranteed end-to-end performance for read-only files with the help of reduced metadata, fixed-sized output compression and decompression inplace technologies. In the past year, EROFS was greatly improved by many people as a staging driver, self-tested, betaed by a large number of our internal users, successfully applied to almost all in-service HUAWEI smartphones as the part of EMUI 9.1 and proven to be stable enough to be moved out of staging. EROFS is a self-contained filesystem driver. Although there are still some TODOs to be more generic, we have a dedicated team actively keeping on working on EROFS in order to make it better with the evolution of Linux kernel as the other in-kernel filesystems. As Pavel suggested, it's better to do as one commit since git can do moves and all histories will be saved in this way. Let's promote it from staging and enhance it more actively as a "real" part of kernel for more wider scenarios!

xprtrdma: Cache free MRs in each rpcrdma_req
Instead of a globally-contended MR free list, cache MRs in each rpcrdma_req as they are released. This means acquiring and releasing an MR will be lock-free in the common case, even outside the transport send lock. The original idea of per-rpcrdma_req MR free lists was suggested by Shirley Ma <shirley.ma@oracle.com> several years ago. I just now figured out how to make that idea work with on-demand MR allocation. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com> |

rxrpc: Fix read-after-free in rxrpc_queue_local()
rxrpc_queue_local() attempts to queue the local endpoint it is given and
then, if successful, prints a trace line. The trace line includes the
current usage count - but we're not allowed to look at the local endpoint
at this point as we passed our ref on it to the workqueue.
Fix this by reading the usage count before queuing the work item.
Also fix the reading of local->debug_id for trace lines, which must be done
with the same consideration as reading the usage count.

rcu/nocb: Use rcu_segcblist for no-CBs CPUs
Currently the RCU callbacks for no-CBs CPUs are queued on a series of ad-hoc linked lists, which means that these callbacks cannot benefit from "drive-by" grace periods, thus suffering needless delays prior to invocation. In addition, the no-CBs grace-period kthreads first wait for callbacks to appear and later wait for a new grace period, which means that callbacks appearing during a grace-period wait can be delayed. These delays increase memory footprint, and could even result in an out-of-memory condition. This commit therefore enqueues RCU callbacks from no-CBs CPUs on the rcu_segcblist structure that is already used by non-no-CBs CPUs. It also restructures the no-CBs grace-period kthread to be checking for incoming callbacks while waiting for grace periods. Also, instead of waiting for a new grace period, it waits for the closest grace period that will cause some of the callbacks to be safe to invoke. All of these changes reduce callback latency and thus the number of outstanding callbacks, in turn reducing the probability of an out-of-memory condition. Signed-off-by: Paul E.

xdp: Add devmap_hash map type for looking up devices by hashed index
A common pattern when using xdp_redirect_map() is to create a device map where the lookup key is simply ifindex. Because device maps are arrays, this leaves holes in the map, and the map has to be sized to fit the largest ifindex, regardless of how many devices actually are actually needed in the map. This patch adds a second type of device map where the key is looked up using a hashmap, instead of being used as an array index. This allows maps to be densely packed, so they can be smaller.

In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads. In addition, we've fixed subtle quota corruption issue. Enhancement: - add swap file support which uses DIO - allocate blocks for pinned file - allow SSR and mount option to enhance checkpoint=disable - enhance IPU IOs - add more sanity checks such as memory boundary access Bug fix: - quota corruption in very corner case of error-injected SPO case - fix root_reserved on remount and some wrong counts - add missing fsck flag Some patches were also introduced to clean up ambiguous i_flags and debugging messages codes. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAl0mlKIACgkQQBSofoJI UNI2Ow//e4QxinKVdgA6F2wx0CkdSreqfzQbA1t+6pcWgzCgLfj4dpOuSp8Yu1NT aG6YFfUxjtUNN8D85WqJ+6qKt0gFBoxjQXDvvbxLFB9Xoa2XqzFrHW8xenSRHppj V63Yye5Z+Qgss65hTktgHMWSi4mUWRq76t1lFBprXm41uC036rIQCSYioztcLQCN fFi2xfkFHf7vIIg6ZrCy22wNSCWL9X6dzKftIZ6LSz+jkPGEard1D/OUYLMMQ4YG b5DS0LEWbudn1vwALPPXwTHgZuG12W581MsHUsu2FIyenGGTk7EIZfNBN6cGfIMk NsEMnanFvXp7ZYP6HQnZlSkoBRIkD2JpYh7bFxTklw4H09GJxYFksed8uqNoDRog GPcNZjKSm0wCUHe2awOhF9kRXMFnwIR7m4DNOQHH1MYmpp3ponGsbfYy3J/qLS5y Smh8pcbsttDMQ0NaWZznby2bSEv9k9R9CoqE5sKCNDnh6Ky8WjK8x6xt3wrPG6h8 jI7venvHvJbFpxAmnKDzflZrlGj95pg0j0DAk07ql/9i8YPfRrlBKv8jOo+7aRWC jIO70URGDO6R/o5XdRqx6u8DOE1JPVP+6XzsT6MdDtBlxE+TbcTPRt3RzEgmo1d3 CI0jq0IRDTDZJITmQoQKCS85OZDyaAe2iHUPwSjCEuDex5lynuY= =S2ZS -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've introduced native swap file support which can exploit DIO, enhanced existing checkpoint=disable feature with additional mount option to tune the triggering condition, and allowed user to preallocate physical blocks in a pinned file which will be useful to avoid f2fs fragmentation in append-only workloads.
