Until now, when VLAN acceleration was in use, the bytes of the VLAN header
were not included in port or flow byte counters. They were however
included when VLAN acceleration was not used. This commit corrects the
inconsistency, by always including the VLAN header in byte counters.

Thomas Jarosch reported IPsec TCP stalls when a PMTU event occurs.
In fact the problem was completely unrelated to IPsec. The bug is
also reproducible if you just disable TSO/GSO.
The problem is that when the MSS goes down, existing queued packet
on the TX queue that have not been transmitted yet all look like
TSO packets and get treated as such.
This then triggers a bug where tcp_mss_split_point tells us to
generate a zero-sized packet on the TX queue. Once that happens
we're screwed because the zero-sized packet can never be removed
by ACKs.
Fixes: 1485348d242 ("tcp: Apply device TSO segment limit earlier")

Previously, mlx4_mt_rereg_write filled the MPT's entity_size with the
old MTT's page shift, which could result in using an incorrect offset.
Fix the initialization to be after we calculate the new MTT offset.
In addition, assign mtt order to -1 after calling mlx4_mtt_cleanup. This
is necessary in order to mark the MTT as invalid and avoid freeing it later.

Commit 1d52c78afbb (Btrfs: try not to ENOSPC on log replay) added a
check to skip delayed inode updates during log replay because it
confuses the enospc code. But the delayed processing will end up
ignoring delayed refs from log replay because the inode itself wasn't
put through the delayed code.
This can end up triggering a warning at commit time:
WARNING: CPU: 2 PID: 778 at fs/btrfs/delayed-inode.c:1410 btrfs_assert_delayed_root_empty+0x32/0x34()
Which is repeated for each commit because we never process the delayed
inode ref update.
The fix used here is to change btrfs_delayed_delete_inode_ref to return
an error if we're currently in log replay. The caller will do the ref
deletion immediately and everything will work properly.

If we are using skinny metadata, the block's tree level is in the offset
of the key and not in a btrfs_tree_block_info structure following the
extent item (it doesn't exist). Therefore fix it.
Besides returning the correct level in the tree, this also prevents reading
past the leaf's end in the case where the extent item is the last item in
the leaf (eb) and it has only 1 inline reference - this is because
sizeof(struct btrfs_tree_block_info) is greater than
sizeof(struct btrfs_extent_inline_ref).
Got it while running a scrub which produced the following warning:

The fix isn't as nice as I would like, as it involves an allocate/copy

Although it doesn't explicitly say so, commit 60ffa478759f39a2 ("e100:

648951451e6d2d53 ("e100: fixed e100 MDI/MDI-X issues"). However,
careful examination reveals that the attempted revert actually
_inverted_ the test for eeprom_mdix_enabled. That is bound to program
a few PHYs incorrectly...

This reverts commit 24a0aa212ee2dbe44360288684478d76a8e20a0a.
It's causing severe userspace breakage. Namely, all the utilities from
wireless-utils which are relying on CONFIG_WEXT (which means tools like
'iwconfig', 'iwlist', etc) are not working anymore. There is a 'iw'
utility in newer wireless-tools, which is supposed to be a replacement
for all the "deprecated" binaries, but it's far away from being
massively adopted.
Please see [1] for example of the userspace breakage this is causing.
In addition to that, Larry Finger reports [2] that this patch is also
causing ipw2200 driver being impossible to build.
To me this clearly shows that CONFIG_WEXT is far, far away from being
"deprecated enough" to be removed.

Commit ac61d1955934 (scsi: set correct completion code in
scsi_send_eh_cmnd()) introduced a bug. It changed the stored return
value from a queuecommand call, but it didn't take into account that
the return value was used again later on. This patch fixes the bug by
changing the later usage.
There is a big comment in the middle of scsi_send_eh_cmnd() which
does a good job of explaining how the routine works. But it mentions
a "rtn = FAILURE" value that doesn't exist in the code. This patch
adjusts the code to match the comment (I assume the comment is right
and the code is wrong).
This fixes Bugzilla #88341.

Currently we enable Exynos devices in the multi v7 defconfig, however, when

Unfortunately, while commit 4a928436 ("audit: correctly record file
names with different path name types") fixed a problem where we were
not recording filenames, it created a new problem by attempting to use
these file names after they had been freed. This patch resolves the
issue by creating a copy of the filename which the audit subsystem
frees after it is done with the string.
At some point it would be nice to resolve this issue with refcounts,
or something similar, instead of having to allocate/copy strings, but
that is almost surely beyond the scope of a -rcX patch so we'll defer
that for later. On the plus side, only audit users should be impacted
by the string copying.

When I/O is aborted by mid-layer, fnic FW will complete the I/O before
completing the abort task. In some cases abort request is completed before
the I/O, which could lead to inconsistent driver and firmware states.
In this case firmware reset would clear the inconsistent state.

7985090aa020 changed the discard heuristics to give preference to the
WRITE SAME commands that (unlike UNMAP) guarantee deterministic results.
Ming Lei discovered that QEMU SCSI's WRITE SAME implementation
internally relied on limits that were only communicated for the UNMAP
case. And therefore discard commands backed by WRITE SAME would fail.
Tweak the heuristics so we still pick UNMAP in the LBPRZ=0 case and only
prefer the WRITE SAME variants if the device has the LBPRZ flag set.

The Rockchip pinctrl driver was only implementing the "mask" and
"unmask" operations though the hardware actually has two distinct
things: enable/disable and mask/unmask. It was implementing the
"mask" operations as a hardware enable/disable and always leaving all
interrupts unmasked.
I believe that the old system had some downsides, specifically:
- (Untested) if an interrupt went off while interrupts were "masked"
it would be lost. Now it will be kept track of.
- If someone wanted to change an interrupt back into a GPIO (is such a
thing sensible?) by calling irq_disable() it wouldn't actually take
effect. That's because Linux does some extra optimizations when
there's no true "disable" function: it does a lazy mask.
Let's actually implement enable/disable/mask/unmask properly.

The rockchip pinctrl driver was using irq_gc_set_wake() as its
implementation of irq_set_wake() but was totally ignoring everything
that irq_gc_set_wake() did (which is to upkeep gc->wake_active).
Let's fix that by setting gc->wake_active as GPIO_INTEN at suspend
time and restoring GPIO_INTEN at resume time.
NOTE a few quirks when thinking about this patch:
- Rockchip pinctrl hardware supports both "disable/enable" and
"mask/unmask". Right now we only use "disable/enable" and present
those to Linux as "mask/unmask". This should be OK because
enable/disable is optional and Linux will implement it in terms of
mask/unmask. At the moment we always tell hardware all interrupts
are unmasked (the boot default).
- At suspend time Linux tries to call "disable" on all interrupts and
also enables wakeup on all wakeup interrupts. One would think that
since "disable" is implemented as "mask" when "disable" isn't
provided and that since we were ignoring gc->wake_active that
nothing would have woken us up. That's not the case since Linux
"optimizes" things and just leaves interrutps unmasked, assuming it
could mask them later when they go off. That meant that at suspend
time all interrupts were actually being left enabled.
With this patch random non-wakeup interrupts no longer wake the system
up. Wakeup interrupts still wake the system up.
