In case of a failed write request (all retries failed) and when using
libata, the SCSI error handler calls scsi_finish_command(). In the
case of blk-mq this means that scsi_mq_done() does not get called,
that blk_mq_complete_request() does not get called and also that the
mq-deadline .completed_request() method is not called. This results in
the target zone of the failed write request being left in a locked
state, preventing that any new write requests are issued to the same
zone.
Fix this by replacing the .completed_request() method with the
.finish_request() method as this method is always called whether or
not a request completes successfully. Since the .finish_request()
method is only called by the blk-mq core if a .prepare_request()
method exists, add a dummy .prepare_request() method.

Currently, sparse issues warnings on code using an attribute
it doesn't know about.
One of the problem with this is that these warnings have no
value for the developer, it's just noise for him. At best these
warnings tell something about some deficiencies of sparse itself
but not about a potential problem with code analyzed.
A second problem with this is that sparse release are, alas,
less frequent than new attributes are added to GCC.
So, avoid the noise by asking sparse to not warn about
attributes it doesn't know about.

The comment above the silentoldconfig invocation is outdated.
'make oldconfig' updates just .config and doesn't touch the
include/config/ tree.
This came up in https://lkml.org/lkml/2018/2/12/415.
While fixing the comment, make it more informative by explaining the
purpose of the unfortunately named silentoldconfig.
I can't make sense of the comment re. auto.conf.cmd and a cleaned tree.
include/config/auto.conf and include/config/auto.conf.cmd are both
created simultaneously by silentoldconfig (in
scripts/kconfig/confdata.c, by conf_write_autoconf()), and nothing seems
to remove auto.conf.cmd that wouldn't remove auto.conf. Remove that part
of the comment rather than blindly copying it. It might be a leftover
from an older way of doing things.
The include/config/auto.conf.cmd prerequisite might be there to ensure
that silentoldconfig gets rerun if conf_write_autoconf() fails between
writing out auto.conf.cmd and auto.conf (a comment in the function
indicates that auto.conf is deliberately written out last to mark
completion of the operation). It seems the Makefile dependency between
include/config/auto.conf and .config would already take care of that
though, since include/config/auto.conf would still be out of date re.
.config if the operation fails.
Cop out and leave the prerequisite in for now.

If we have a file with 2 (or more) hard links in the same directory,
remove one of the hard links, create a new file (or link an existing file)
in the same directory with the name of the removed hard link, and then
finally fsync the new file, we end up with a log that fails to replay,
causing a mount failure.
Example:
$ mkfs.btrfs -f /dev/sdb
$ mount /dev/sdb /mnt
$ mkdir /mnt/testdir
$ touch /mnt/testdir/foo
$ ln /mnt/testdir/foo /mnt/testdir/bar
$ sync
$ unlink /mnt/testdir/bar
$ touch /mnt/testdir/bar
$ xfs_io -c "fsync" /mnt/testdir/bar
<power failure>
$ mount /dev/sdb /mnt
mount: mount(2) failed: /mnt: No such file or directory
When replaying the log, for that example, we also see the following in

This happens because the log has inode reference items for both inode 258
(the first file we created) and inode 259 (the second file created), and
when processing the reference item for inode 258, we replace the
corresponding item in the subvolume tree (which has two names, "foo" and
"bar") witht he one in the log (which only has one name, "foo") without
removing the corresponding dir index keys from the parent directory.
Later, when processing the inode reference item for inode 259, which has
a name of "bar" associated to it, we notice that dir index entries exist
for that name and for a different inode, so we attempt to unlink that
name, which fails because the inode reference item for inode 258 no longer
has the name "bar" associated to it, making a call to btrfs_unlink_inode()
fail with a -ENOENT error.
Fix this by unlinking all the names in an inode reference item from a
subvolume tree that are not present in the inode reference item found in
the log tree, before overwriting it with the item from the log tree.

If in the same transaction we rename a special file (fifo, character/block
device or symbolic link), create a hard link for it having its old name
then sync the log, we will end up with a log that can not be replayed and
at when attempting to replay it, an EEXIST error is returned and mounting
the filesystem fails. Example scenario:
$ mkfs.btrfs -f /dev/sdc
$ mount /dev/sdc /mnt
$ mkdir /mnt/testdir
$ mkfifo /mnt/testdir/foo
# Make sure everything done so far is durably persisted.
$ sync
# Create some unrelated file and fsync it, this is just to create a log
# tree. The file must be in the same directory as our special file.
$ touch /mnt/testdir/f1
$ xfs_io -c "fsync" /mnt/testdir/f1
# Rename our special file and then create a hard link with its old name.
$ mv /mnt/testdir/foo /mnt/testdir/bar
$ ln /mnt/testdir/bar /mnt/testdir/foo
# Create some other unrelated file and fsync it, this is just to persist
# the log tree which was modified by the previous rename and link
# operations. Alternatively we could have modified file f1 and fsync it.
$ touch /mnt/f2
$ xfs_io -c "fsync" /mnt/f2
<power failure>
$ mount /dev/sdc /mnt
mount: mount /dev/sdc on /mnt failed: File exists
This happens because when both the log tree and the subvolume's tree have
an entry in the directory "testdir" with the same name, that is, there
is one key (258 INODE_REF 257) in the subvolume tree and another one in
the log tree (where 258 is the inode number of our special file and 257
is the inode for directory "testdir"). Only the data of those two keys
differs, in the subvolume tree the index field for inode reference has
a value of 3 while the log tree it has a value of 5. Because the same key
exists in both trees, but have different index, the log replay fails with
an -EEXIST error when attempting to replay the inode reference from the
log tree.
Fix this by setting the last_unlink_trans field of the inode (our special
file) to the current transaction id when a hard link is created, as this
forces logging the parent directory inode, solving the conflict at log
replay time.
A new generic test case for fstests was also submitted.

When doing an incremental send of a filesystem with the no-holes feature
enabled, we end up issuing a write operation when using the no data mode
send flag, instead of issuing an update extent operation. Fix this by
issuing the update extent operation instead.
Trivial reproducer:
$ mkfs.btrfs -f -O no-holes /dev/sdc
$ mkfs.btrfs -f /dev/sdd
$ mount /dev/sdc /mnt/sdc

$ xfs_io -f -c "pwrite -S 0xab 0 32K" /mnt/sdc/foobar
$ btrfs subvolume snapshot -r /mnt/sdc /mnt/sdc/snap1
$ xfs_io -c "fpunch 8K 8K" /mnt/sdc/foobar
$ btrfs subvolume snapshot -r /mnt/sdc /mnt/sdc/snap2
$ btrfs send /mnt/sdc/snap1 | btrfs receive /mnt/sdd
$ btrfs send --no-data -p /mnt/sdc/snap1 /mnt/sdc/snap2 \
| btrfs receive -vv /mnt/sdd

The fs_info::super_copy is a byte copy of the on-disk structure and all
members must use the accessor macros/functions to obtain the right
value. This was missing in update_super_roots and in sysfs readers.
Moving between opposite endianness hosts will report bogus numbers in
sysfs, and mount may fail as the root will not be restored correctly. If
the filesystem is always used on a same endian host, this will not be a
problem.
Fix this by using the btrfs_set_super...() functions to set
fs_info::super_copy values, and for the sysfs, use the cached
fs_info::nodesize/sectorsize values.

In case of using DUP, we search for enough unallocated disk space on a
device to hold two stripes.
The devices_info[ndevs-1].max_avail that holds the amount of unallocated
space found is directly assigned to stripe_size, while it's actually
twice the stripe size.
Later on in the code, an unconditional division of stripe_size by
dev_stripes corrects the value, but in the meantime there's a check to
see if the stripe_size does not exceed max_chunk_size. Since during this
check stripe_size is twice the amount as intended, the check will reduce
the stripe_size to max_chunk_size if the actual correct to be used
stripe_size is more than half the amount of max_chunk_size.
The unconditional division later tries to correct stripe_size, but will
actually make sure we can't allocate more than half the max_chunk_size.
Fix this by moving the division by dev_stripes before the max chunk size
check, so it always contains the right value, instead of putting a duct
tape division in further on to get it fixed again.
Since in all other cases than DUP, dev_stripes is 1, this change only
affects DUP.
Other attempts in the past were made to fix this:
* 37db63a400 "Btrfs: fix max chunk size check in chunk allocator" tried
to fix the same problem, but still resulted in part of the code acting
on a wrongly doubled stripe_size value.
* 86db25785a "Btrfs: fix max chunk size on raid5/6" unintentionally
broke this fix again.
The real problem was already introduced with the rest of the code in
73c5de0051.
The user visible result however will be that the max chunk size for DUP
will suddenly double, while it's actually acting according to the limits
in the code again like it was 5 years ago.

add_pending_csums was added as part of the new data=ordered
implementation in e6dcd2dc9c ("Btrfs: New data=ordered
implementation"). Even back then it called the btrfs_csum_file_blocks
which can fail but it never bothered handling the failure. In ENOMEM
situation this could lead to the filesystem failing to write the
checksums for a particular extent and not detect this. On read this
could lead to the filesystem erroring out due to crc mismatch. Fix it by
propagating failure from add_pending_csums and handling them.

The srcu_struct in btrfs_fs_info scales in size with NR_CPUS. On
kernels built with NR_CPUS=8192, this can result in kmalloc failures
that prevent mounting.
There is work in progress to try to resolve this for every user of
srcu_struct but using kvzalloc will work around the failures until
that is complete.
As an example with NR_CPUS=512 on x86_64: the overall size of
subvol_srcu is 3460 bytes, fs_info is 6496.

The separation of the cpu_entry_area from the fixmap missed the fact that
on 32bit non-PAE kernels the cpu_entry_area mapping might not be covered in
initial_page_table by the previous synchronizations.
This results in suspend/resume failures because 32bit utilizes initial page
table for resume. The absence of the cpu_entry_area mapping results in a
triple fault, aka. insta reboot.
With PAE enabled this works by chance because the PGD entry which covers
the fixmap and other parts incindentally provides the cpu_entry_area
mapping as well.
Synchronize the initial page table after setting up the cpu entry
area. Instead of adding yet another copy of the same code, move it to a
function and invoke it from the various places.
It needs to be investigated if the existing calls in setup_arch() and
setup_per_cpu_areas() can be replaced by the later invocation from
setup_cpu_entry_areas(), but that's beyond the scope of this fix.

riscv/barrier: Define __smp_{mb,rmb,wmb}
On CPU hotunplug the enqueued timers of the unplugged CPU are migrated to a
live CPU. This happens from the control thread which initiated the unplug.
If the CPU on which the control thread runs came out from a longer idle
period then the base clock of that CPU might be stale because the control
thread runs prior to any event which forwards the clock.
In such a case the timers from the unplugged CPU are queued on the live CPU
based on the stale clock which can cause large delays due to increased
granularity of the outer timer wheels which are far away from base:;clock.
But there is a worse problem than that. The following sequence of events
illustrates it:
- CPU0 timer1 is queued expires = 59969 and base->clk = 59131.
The timer is queued at wheel level 2, with resulting expiry time = 60032
(due to level granularity).
- CPU1 enters idle @60007, with next timer expiry @60020.
- CPU0 is hotplugged at @60009
- CPU1 exits idle and runs the control thread which migrates the
timers from CPU0
timer1 is now queued in level 0 for immediate handling in the next
softirq because the requested expiry time 59969 is before CPU1 base->clk
60007
- CPU1 runs code which forwards the base clock which succeeds because the
next expiring timer. which was collected at idle entry time is still set
to 60020.
So it forwards beyond 60007 and therefore misses to expire the migrated
timer1. That timer gets expired when the wheel wraps around again, which
takes between 63 and 630ms depending on the HZ setting.
Address both problems by invoking forward_timer_base() for the control CPUs
timer base. All other places, which might run into a similar problem
(mod_timer()/add_timer_on()) already invoke forward_timer_base() to avoid
that.

Currently all cursor related functions are made to all
pipes that are attached to a particular stream.
This is not applicable to pipes that do not have cursor plane
initialised like underlay.
Hence this patch allows cursor related operations on a pipe
only if ipp in available on that particular pipe.
The check is added to set_cursor_position & set_cursor_attribute.

A toolstack may delete the vif frontend and backend xenstore entries
while xen-netfront is in the removal code path. In that case, the
checks for xenbus_read_driver_state would return XenbusStateUnknown, and
xennet_remove would hang indefinitely. This hang prevents system
shutdown.
xennet_remove must be able to handle XenbusStateUnknown, and
netback_changed must also wake up the wake_queue for that state as well.

Current cleanup in the error path of xen_bind_pirq_msi_to_irq is
wrong. First of all there's an off-by-one in the cleanup loop, which
can lead to unbinding wrong IRQs.
Secondly IRQs not bound won't be freed, thus leaking IRQ numbers.
Note that there's no need to differentiate between bound and unbound
IRQs when freeing them, __unbind_from_irq will deal with both of them
correctly.
