The function xfs_bmap_isaeof() is used to indicate that an
allocation is occurring at or past the end of file, and as such
should be aligned to the underlying storage geometry if possible.
Commit 27a3f8f ("xfs: introduce xfs_bmap_last_extent") changed the
behaviour of this function for empty files - it turned off
allocation alignment for this case accidentally. Hence large initial
allocations from direct IO are not getting correctly aligned to the
underlying geometry, and that is cause write performance to drop in
alignment sensitive configurations.
Fix it by considering allocation into empty files as requiring
aligned allocation again.

If we are using a large directory block size, and memory becomes
fragmented, we can get memory allocation failures trying to
kmem_alloc(64k) for a temporary buffer. However, there is not need
for a directory buffer sized allocation, as the end result ends up
in the inode literal area. This is, at most, slightly less than 2k
of space, and hence we don't need an allocation larger than that
fora temporary buffer.

It's fine if we turn user quota off at first, then turn off other
kind of quotas if they are enabled since the group/project dquot
refcount is decreased to zero once the user quota if off. Otherwise,
those dquots refcount is non-zero due to the user dquot might refer
to them as hint(s). Hence, above operation cause an infinite loop
at xfs_qm_dquot_walk() while trying to purge dquot cache.
This problem has been around since Linux 3.4, it was introduced by:
[ b84a3a9675 xfs: remove the per-filesystem list of dquots ]
Originally we will release the group dquot pointers because the user
dquots maybe carrying around as a hint via xfs_qm_detach_gdquots().
However, with above change, there is no such work to be done before
purging group/project dquot cache.
In order to solve this problem, this patch introduces a special routine
xfs_qm_dqpurge_hints(), and it would release the group/project dquot
pointers the user dquots maybe carrying around as a hint, and then it
will proceed to purge the user dquot cache if requested.

We're hitting the ASSERT(XFS_IS_*QUOTA_ON(mp)) in xfs_qm_vop_create_dqattach(),
however the assertion itself is not right IMHO. While performing quota off, we
firstly clear the XFS_*QUOTA_ACTIVE bit(s) from struct xfs_mount without taking
any special locks, see xfs_qm_scall_quotaoff(). Hence there is no guarantee
that the desired quota is still active.

In xfs_qm_scall_trunc_qfiles(), we ignore the error if failed to remove
the users quota metadata and proceed to remove groups and projects if
they are being there. However, in user space, the remove operation will
break and return if failed to remove any kind of quota.
Also for v5 super block, we can enabled both group and project quota at
the same time, in this case the current error handling will cover the
group error with projects but they might failed due to different reasons.
It seems we'd better the error handling consistent to the user space and
don't trying to remove another kind of quota metadata if the previous
operation is failed.

Recovery builds a list of items on the transaction's

But in the event of a recovery error, these allocations
are leaked.
If the error occurs during item reordering, then reconstruct

Currently notify_change directly updates i_version for size updates,
which not only is counter to how all other fields are updated through
struct iattr, but also breaks XFS, which need inode updates to happen
under its own lock, and synchronized to the structure that gets written
to the log.
Remove the update in the common code, and it to btrfs and ext4,
XFS already does a proper updaste internally and currently gets a
double update with the existing code.
IMHO this is 3.13 and -stable material and should go in through the XFS
tree.

This loop in xfs_growfs_data_private() is incorrect for V4
superblocks filesystems:
for (bucket = 0; bucket < XFS_AGFL_SIZE(mp); bucket++)
agfl->agfl_bno[bucket] = cpu_to_be32(NULLAGBLOCK);
For V4 filesystems, we don't have a agfl header structure, and so
XFS_AGFL_SIZE() returns an entire sector's worth of entries, which
we then index from an offset into the sector. Hence: buffer overrun.
This problem was introduced in 3.10 by commit 77c95bba ("xfs: add
CRC checks to the AGFL") which changed the AGFL structure but failed
to update the growfs code to handle the different structures.
Fix it by using the correct offset into the buffer for both V4 and
V5 filesystems.

PTE_PROT_NONE means that a pte is present but does not have any
read/write attributes. However, setting the memory type like
pgprot_writecombine() is allowed and such bits overlap with
PTE_PROT_NONE. This causes mmap/munmap issues in drivers that change the
vma->vm_pg_prot on PROT_NONE mappings.
This patch reverts the PTE_FILE/PTE_PROT_NONE shift in commit
59911ca4325d (ARM64: mm: Move PTE_PROT_NONE bit) and moves PTE_PROT_NONE
together with the other software bits.

Pull GPIO fixes from Linus Walleij:
"Here us a bunch of patches for the v3.13 series. Most important stuff
is related to fixes and documentation for the new GPIO descriptor API.
If the diffstat is scary you'll notice most of it is to
Documentation/*:
- A big slew of documentation for the gpiod transition that happened
in the merge window, no semantic effect, but we should provide
proper documentation with the new API.
- Fix flags related to the new API.
- Fix to the find_chip_by_name() lookup function related to the new
API.
- Fix of_find_gpio() when not using device tree.
- Bug fix for the TB10x direction setting.
- Error path fixes from Dan Carpenter.
- Nasty IRQdomain bug relating to taking an unitialized spinlock.
- Minor fixes here and there"

Pull cifs fixes from Steve French:
"SMB3 "validate negotiate" is needed to prevent certain types of
downgrade attacks.
Also changes SMB2/SMB3 copy offload from using the BTRFS copy ioctl
(BTRFS_IOC_CLONE) to a cifs specific ioctl (CIFS_IOC_COPYCHUNK_FILE)
to address Christoph's comment that there are semantic differences
between requesting copy offload in which copy-on-write is mandatory
(as in the BTRFS ioctl) and optional in the SMB2/SMB3 case. Also
fixes SMB2/SMB3 copychunk for large files"
* 'for-next' of git://git.samba.org/sfrench/cifs-2.6:
[CIFS] Do not use btrfs refcopy ioctl for SMB2 copy offload
Check SMB3 dialects against downgrade attacks
Removed duplicated (and unneeded) goto

As the previous commit 1f0bbf03cb82 added the pin config for the bass

Add a fixup entry for the missing bass speaker pin 0x16 on ASUS ET2700
AiO desktop. The channel map will be added in the next patch, so that
this can be backported easily to stable kernels.

The current generic parser assumes blindly that the volume and mute
amps are found in the aamix node itself. But on some codecs,
typically Analog Devices ones, the aamix amps are separately
implemented in each leaf node of the aamix node, and the current
driver can't establish the correct amp controls. This is a regression
compared with the previous static quirks.
This patch extends the search for the amps to the leaf nodes for
allowing the aamix controls again on such codecs.
In this implementation, I didn't code to loop through the whole paths,
since usually one depth should suffice, and we can't search too
deeply, as it may result in the conflicting control assignments.
