db62efbbf8 btrfs: don't loop on large offsets in readdir
When btrfs readdir() hits the last entry it sets the readdir offset to a
huge value to stop buggy apps from breaking when the same name is
returned by readdir() with concurrent rename()s.

But unconditionally setting the offset to INT_MAX causes readdir() to
loop returning any entries with offsets past INT_MAX.  It only takes a
few hours of constant file creation and removal to create entries past
INT_MAX.

So let's set the huge offset to LLONG_MAX if the last entry has already
overflowed 32bit loff_t.   Without large offsets behaviour is identical.
With large offsets 64bit apps will work and 32bit apps will be no more
broken than they currently are if they see large offsets.

f3b15ccdbb Btrfs: release both paths before logging dir/changed extents
The ceph guys tripped over this bug where we were still holding onto the
original path that we used to copy the inode with when logging.  This is based
on Chris's fix which was reported to fix the problem.  We need to drop the paths
in two cases anyway so just move the drop up so that we don't have duplicate
code.  Thanks,

ee20a98314 Btrfs: allow splitting of hole em's when dropping extent cache
I noticed while running multi-threaded fsync tests that sometimes fsck would
complain about an improper gap.  This happens because we fail to add a hole
extent to the file, which was happening when we'd split a hole EM because
btrfs_drop_extent_cache was just discarding the whole em instead of splitting
it.  So this patch fixes this by allowing us to split a hole em properly, which
means that added holes actually get logged properly and we no longer see this
fsck error.  Thankfully we're tolerant of these sort of problems so a user would
not see any adverse effects of this bug, other than fsck complaining.  Thanks,

ed8c4913da Btrfs: make sure the backref walker catches all refs to our extent
Because we don't mess with the offset into the extent for compressed we will
properly find both extents for this case

[extent a][extent b][rest of extent a]

but because we already added a ref for the front half we won't add the inode
information for the second half.  This causes us to leak that memory and not
print out the other offset when we do logical-resolve.  So fix this by calling
ulist_add_merge and then add our eie to the existing entry if there is one.
With this patch we get both offsets out of logical-resolve.  With this and the
other 2 patches I've sent we now pass btrfs/276 on my vm with compress-force=lzo
set.  Thanks,

8ca15e05e6 Btrfs: fix backref walking when we hit a compressed extent
If you do btrfs inspect-internal logical-resolve on a compressed extent that has
been partly overwritten it won't find anything.  This is because we try and
match the extent offset we've searched for based on the extent offset in the
data extent entry.  However this doesn't work for compressed extents because the
offsets are for the uncompressed size, not the compressed size.  So instead only
do this check if we are not compressed, that way we can get an actual entry for
the physical offset rather than nothing for compressed.  Thanks,

b76bb70136 Btrfs: do not offset physical if we're compressed
xfstest btrfs/276 was freaking out on slower boxes partly because fiemap was
offsetting the physical based on the extent offset.  This is perfectly fine with
uncompressed extents, however the extent offset is into the uncompressed area,
not the compressed.  So we can return a physical value that isn't at all within
the area we have allocated on disk.  Fix this by returning the start of the
extent if it is compressed no matter what the offset.  Thanks,

e68afa49ae Btrfs: fix a bug of snapshot-aware defrag to make it work on partial extents
For partial extents, snapshot-aware defrag does not work as expected,
since
a) we use the wrong logical offset to search for parents, which should be
   disk_bytenr + extent_offset, not just disk_bytenr,
b) 'offset' returned by the backref walking just refers to key.offset, not
   the 'offset' stored in btrfs_extent_data_ref which is
   (key.offset - extent_offset).

The reproducer:
$ mkfs.btrfs sda
$ mount sda /mnt
$ btrfs sub create /mnt/sub
$ for i in `seq 5 -1 1`; do dd if=/dev/zero of=/mnt/sub/foo bs=5k count=1 seek=$i conv=notrunc oflag=sync; done
$ btrfs sub snap /mnt/sub /mnt/snap1
$ btrfs sub snap /mnt/sub /mnt/snap2
$ sync; btrfs filesystem defrag /mnt/sub/foo;
$ umount /mnt
$ btrfs-debug-tree sda (Here we can check whether the defrag operation is snapshot-awared.

This addresses the above two problems.

14e94194d1 ACPI and power management fixes for 3.11-rc5
- ACPI-based memory hotplug stopped working after a recent change,
   because it's not possible to associate sufficiently many "physical"
   devices with one ACPI device object due to an artificial limit.
   Fix from Rafael J Wysocki removes that limit and makes memory
   hotplug work again.
 
 - A change made in 3.9 uncovered a bug in the ACPI processor driver
   preventing NUMA nodes from being put offline due to an ordering
   issue.  Fix from Yasuaki Ishimatsu changes the ordering to make
   things work again.
 
 - One of the recent ACPI video commits (that hasn't been reverted
   so far) uncovered a bug in the code handling quirky BIOSes that
   caused some Asus machines to boot with backlight completely off
   which made it quite difficult to use them afterward.  Fix from
   Felipe Contreras improves the quirk to cover this particular
   case correctly.
 
 - A cpufreq user space interface change made in 3.10 inadvertently
   renamed the ignore_nice_load sysfs attribute to ignore_nice which
   resulted in some confusion.  Fix from Viresh Kumar changes the name
   back to ignore_nice_load.
 
 - An initialization ordering change made in 3.9 broke cpufreq on
   loongson2 boards.  Fix from Aaro Koskinen restores the correct
   initialization ordering there.
 
 - Fix breakage resulting from a mistake made in 3.9 and causing the
   detection of some graphics adapters (that were detected correctly
   before) to fail.  There are two objects representing the same PCIe
   port in the affected systems' ACPI tables and both appear as
   "enabled" and we are expected to guess which one to use.  We used
   to choose the right one before by pure luck, but when we tried to
   address another similar corner case, the luck went away.  This time
   we try to make our guessing a bit more educated which is reported
   to work on those systems.
 
 - The /proc/acpi/wakeup interface code is missing some locking
   which may lead to breakage if that file is written or read during
   hotplug of wakeup devices.  That should be rare but still possible,
   so it's better to start using the appropriate locking there.

Merge tag 'pm+acpi-3.11-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management fixes from Rafael Wysocki:

 - ACPI-based memory hotplug stopped working after a recent change,
   because it's not possible to associate sufficiently many "physical"
   devices with one ACPI device object due to an artificial limit.  Fix
   from Rafael J Wysocki removes that limit and makes memory hotplug
   work again.

 - A change made in 3.9 uncovered a bug in the ACPI processor driver
   preventing NUMA nodes from being put offline due to an ordering
   issue.  Fix from Yasuaki Ishimatsu changes the ordering to make
   things work again.

 - One of the recent ACPI video commits (that hasn't been reverted so
   far) uncovered a bug in the code handling quirky BIOSes that caused
   some Asus machines to boot with backlight completely off which made
   it quite difficult to use them afterward.  Fix from Felipe Contreras
   improves the quirk to cover this particular case correctly.

 - A cpufreq user space interface change made in 3.10 inadvertently
   renamed the ignore_nice_load sysfs attribute to ignore_nice which
   resulted in some confusion.  Fix from Viresh Kumar changes the name
   back to ignore_nice_load.

 - An initialization ordering change made in 3.9 broke cpufreq on
   loongson2 boards.  Fix from Aaro Koskinen restores the correct
   initialization ordering there.

 - Fix breakage resulting from a mistake made in 3.9 and causing the
   detection of some graphics adapters (that were detected correctly
   before) to fail.  There are two objects representing the same PCIe
   port in the affected systems' ACPI tables and both appear as
   "enabled" and we are expected to guess which one to use.  We used to
   choose the right one before by pure luck, but when we tried to
   address another similar corner case, the luck went away.  This time
   we try to make our guessing a bit more educated which is reported to
   work on those systems.

 - The /proc/acpi/wakeup interface code is missing some locking which
   may lead to breakage if that file is written or read during hotplug
   of wakeup devices.  That should be rare but still possible, so it's
   better to start using the appropriate locking there.

201d3dfa4d dlm: kill the unnecessary and wrong device_close()->recalc_sigpending()
device_close()->recalc_sigpending() is not needed, sigprocmask() takes
care of TIF_SIGPENDING correctly.

And without ->siglock it is racy and wrong, it can wrongly clear
TIF_SIGPENDING and miss a signal.

But even with this patch device_close() is still buggy:

  1. sigprocmask() should not be used, we have set_task_blocked(),
     but this is minor.

  2. We should never block SIGKILL or SIGSTOP, and this is what
     the code tries to do.

  3. This can't protect against SIGKILL or SIGSTOP anyway. Another
     thread can do signal_wake_up(), say, do_signal_stop() or
     complete_signal() or debugger.

  4. sigprocmask(SIG_BLOCK, allsigs) doesn't necessarily clears
     TIF_SIGPENDING, say, freezing() or ->jobctl.

  5. device_write() looks equally wrong by the same reason.

Looks like, this tries to protect some wait_event_interruptible() logic
from signals, it should be turned into uninterruptible wait.  Or we need
to implement something like signals_stop/start for such a use-case.

8e5654ce69 Revert "HID: hid-logitech-dj: querying_devices was never set"
This reverts commit 407a2c2a4d.

Explanation provided by Benjamin Tissoires:

Commit "HID: hid-logitech-dj, querying_devices was never set" activate
a flag which guarantees that we do not ask the receiver for too many
enumeration. When the flag is set, each following enumeration call is
discarded (the usb request is not forwarded to the receiver). The flag
is then released when the driver receive a pairing information event,
which normally follows the enumeration request.
However, the USB3 bug makes the driver think the enumeration request
has been forwarded to the receiver. However, it is actually not the
case because the USB stack returns -EPIPE. So, when a new unknown
device appears, the workaround consisting in asking for a new
enumeration is not working anymore: this new enumeration is discarded
because of the flag, which is never reset.

A solution could be to trigger a timeout before releasing it, but for
now, let's just revert the patch.

93d783bcca hwmon: (adt7470) Fix incorrect return code check
In adt7470_write_word_data(), which writes two bytes using
i2c_smbus_write_byte_data(), the return codes are incorrectly AND-ed
together when they should be OR-ed together.

The return code of i2c_smbus_write_byte_data() is zero for success.

The upshot is only the first byte was ever written to the hardware.
The 2nd byte was never written out.

I noticed that trying to set the fan speed limits was not working
correctly on my system.  Setting the fan speed limits is the only
code that uses adt7470_write_word_data().  After making the change
the limit settings work and the alarms work also.

370905069c Revert "slub: do not put a slab to cpu partial list when cpu_partial is 0"
This reverts commit 318df36e57.

This commit caused Steven Rostedt's hackbench runs to run out of memory
due to a leak.  As noted by Joonsoo Kim, it is buggy in the following
scenario:

 "I guess, you may set 0 to all kmem caches's cpu_partial via sysfs,
  doesn't it?

  In this case, memory leak is possible in following case.  Code flow of
  possible leak is follwing case.

   * in __slab_free()
   1. (!new.inuse || !prior) && !was_frozen
   2. !kmem_cache_debug && !prior
   3. new.frozen = 1
   4. after cmpxchg_double_slab, run the (!n) case with new.frozen=1
   5. with this patch, put_cpu_partial() doesn't do anything,
      because this cache's cpu_partial is 0
   6. return

  In step 5, leak occur"

And Steven does indeed have cpu_partial set to 0 due to RT testing.

Joonsoo is cooking up a patch, but everybody agrees that reverting this
for now is the right thing to do.

57e6dae108 ALSA: usb-audio: do not trust too-big wMaxPacketSize values
The driver used to assume that the streaming endpoint's wMaxPacketSize
value would be an indication of how much data the endpoint expects or
sends, and compute the number of packets per URB using this value.

However, the Focusrite Scarlett 2i4 declares a value of 1024 bytes,
while only about 88 or 44 bytes are be actually used.  This discrepancy
would result in URBs with far too few packets, which would not work
correctly on the EHCI driver.

To get correct URBs, use wMaxPacketSize only as an upper limit on the
packet size.

b72888cb0b NFSv4: Fix up nfs4_proc_lookup_mountpoint
Currently, we do not check the return value of client = rpc_clone_client(),
nor do we shut down the resulting cloned rpc_clnt in the case where a
NFS4ERR_WRONGSEC has caused nfs4_proc_lookup_common() to replace the
original value of 'client' (causing a memory leak).

Fix both issues and simplify the code by moving the call to
rpc_clone_client() until after nfs4_proc_lookup_common() has
done its business.

e91abf80a0 drm: Don't pass negative delta to ktime_sub_ns()
It takes an unsigned value. This happens not to blow up on 64-bit
architectures, but it does on 32-bit, causing
drm_calc_vbltimestamp_from_scanoutpos() to calculate totally bogus
timestamps for vblank events. Which in turn causes e.g. gnome-shell to
hang after a DPMS off cycle with current xf86-video-ati Git.
