The size is always valid, but variable-length arrays generate worse code
for no good reason (unless the function happens to be inlined and the
compiler sees the length for the simple constant it is).Also, there seems to be some code generation problem on POWER, where
Henrik Bakken reports that register r28 can get corrupted under some
subtle circumstances (interrupt happening at the wrong time?). That all
indicates some seriously broken compiler issues, but since variable
length arrays are bad regardless, there's little point in trying to
chase it down."Just don't do that, then".

SFI tables reside in RAM and should not be modified once they are
written. Current code went to set pentry->irq to zero which causes
subsequent reads to fail with invalid SFI table checksum. This will
break kexec as the second kernel fails to validate SFI tables.To fix this we use temporary variable for irq number.

The w83627ehf driver is improperly reporting thermal diode sensors as
type 2, instead of 3. This caused "sensors" and possibly other
monitoring tools to report these sensors as "transistor" instead of
"thermal diode".Furthermore, diode subtype selection (CPU vs. external) is only
supported by the original W83627EHF/EHG. All later models only support
CPU diode type, and some (NCT6776F) don't even have the register in
question so we should avoid reading from it.Signed-off-by: Jean Delvare

With commit f64ad1a0e21a, "gpio/omap: cleanup _set_gpio_wakeup(), remove
ifdefs", access to build time conditionally omitted 'suspend_wakeup'
member of the 'gpio_bank' structure has been placed unconditionally in
function _set_gpio_wakeup(), which is always built. This resulted in the
driver compilation broken for certain OMAP1, i.e., non-OMAP16xx,
configurations.Really required or not in previously excluded cases, define this
structure member unconditionally as a fix.Tested with a custom OMAP1510 only configuration.

Currently we have a few issues with the way the workqueue code is used to
implement AIL pushing:- it accidentally uses the same workqueue as the syncer action, and thus
can be prevented from running if there are enough sync actions active
in the system.
- it doesn't use the HIGHPRI flag to queue at the head of the queue of
work itemsAt this point I'm not confident enough in getting all the workqueue flags and
tweaks right to provide a perfectly reliable execution context for AIL
pushing, which is the most important piece in XFS to make forward progress
when the log fills.Revert back to use a kthread per filesystem which fixes all the above issues
at the cost of having a task struct and stack around for each mounted
filesystem. In addition this also gives us much better ways to diagnose
any issues involving hung AIL pushing and removes a small amount of code.Signed-off-by: Christoph Hellwig

We need to check for pinned buffers even in .iop_pushbuf given that inode
items flush into the same buffers that may be pinned directly due operations
on the unlinked inode list operating directly on buffers. To do this add a
return value to .iop_pushbuf that tells the AIL push about this and use
the existing log force mechanisms to unpin it.Signed-off-by: Christoph Hellwig

If an item was locked we should not update xa_last_pushed_lsn and thus skip
it when restarting the AIL scan as we need to be able to lock and write it
out as soon as possible. Otherwise heavy lock contention might starve AIL
pushing too easily, especially given the larger backoff once we moved
xa_last_pushed_lsn all the way to the target lsn.Signed-off-by: Christoph Hellwig

The btrfs file defrag code will loop through the extents and
force COW on them. But there is a concurrent truncate in the middle of
the defrag, it might end up defragging the same range over and over
again.The problem is that writepage won't go through and do anything on pages
past i_size, so the cow won't happen, so the file will appear to still
be fragmented. defrag will end up hitting the same extents again and
again.In the worst case, the truncate can actually live lock with the defrag
because the defrag keeps creating new ordered extents which the truncate
code keeps waiting on.The fix here is to make defrag check for i_size inside the main loop,
instead of just once before the looping starts.Signed-off-by: Chris Mason

Follow those steps:
# mount -o autodefrag /dev/sda7 /mnt
# dd if=/dev/urandom of=/mnt/tmp bs=200K count=1
# sync
# dd if=/dev/urandom of=/mnt/tmp bs=8K count=1 conv=notruncand then it'll go into a loop: writeback -> defrag -> writeback ...
It's because writeback writes [8K, 200K] and then writes [0, 8K].
I tried to make writeback know if the pages are dirtied by defrag,
but the patch was a bit intrusive. Here I simply set writeback_index
when we defrag a file.Signed-off-by: Li Zefan

The doorbell register was being unconditionally swapped. In x86, that
meant it was being swapped to BE and written to the descriptor and to
memory, depending on the case of blue frame support or writing to
doorbell register. On PPC, this meant it was being swapped to LE and
then swapped back to BE while writing to the register. But in the blue
frame case, it was being written as LE to the descriptor.The fix is not to swap doorbell unconditionally, write it to the
register as BE and convert it to BE when writing it to the descriptor.Signed-off-by: Thadeu Lima de Souza Cascardo

A couple of changes to the Tegra maintainership setup:
I'm very glad to bring on Stephen Warren on board as a maintainer. The
work he has done so far is excellent, and the fact that he works for
Nvidia means he has long-term interest in the platform.Erik Gilling did an astounding amount of work on getting things up and
running but has been a silent partner on the maintainership side for a
while, and is stepping down. Thanks for your contributions so far, Erik.Finally, update the git URL since I'll take over running the main repo
for a while.Overall maintainership model isn't changing much at this time: We'll all
three review patches as appropriate, and one of us will collect the main
repo (me at this time).Signed-off-by: Olof Johansson
