reviews and includes mostly nvme anyway, please tell me if
you don't want to take them with this.

This includes:
- quiesce/unquiesce fixes in nvme and others from me
- nvme-fc add create association padding spec updates from James
- some more quirking from MKP
- nvmet nit cleanup from Max
- Fix nvme-rdma racy RDMA completion signalling from Marta
- some centralization patches from me
- add tagset nr_hw_queues updates on controller resets in
  nvme drivers from me
- nvme-rdma fix resources recycling when doing error recovery from me
- minor cleanups in nvme-fc from me

ff0fa73247 btrfs: nowait aio: Correct assignment of pos
Assigning pos for usage early messes up in append mode, where the pos is
re-assigned in generic_write_checks(). Assign pos later to get the
correct position to write from iocb->ki_pos.

Since check_can_nocow also uses the value of pos, we shift
generic_write_checks() before check_can_nocow(). Checks with IOCB_DIRECT
are present in generic_write_checks(), so checking for IOCB_NOWAIT is
enough.

Also, put locking sequence in the fast path.

This fixes a user visible bug, as reported:

"apparently breaks several shell related features on my system.
In zsh history stopped working, because no new entries are added
anymore.
I fist noticed the issue when I tried to build mplayer. It uses a shell
script to generate a help_mp.h file:
[...]

Here is a simple testcase:

 % echo "foo" >> test
 % echo "foo" >> test
 % cat test
 foo

d3e3b7eac8 afs: Add metadata xattrs
Add xattrs to allow the user to get/set metadata in lieu of having pioctl()
available.  The following xattrs are now available:

 - "afs.cell"

   The name of the cell in which the vnode's volume resides.

 - "afs.fid"

   The volume ID, vnode ID and vnode uniquifier of the file as three hex
   numbers separated by colons.

 - "afs.volume"

   The name of the volume in which the vnode resides.

For example:

	# getfattr -d -m ".*" /mnt/scratch
	getfattr: Removing leading '/' from absolute path names
	# file: mnt/scratch
	afs.cell="mycell.myorg.org"
	afs.fid="10000b:1:1"

fd2498211a afs: Ignore AFS_ACE_READ and AFS_ACE_WRITE for directories
The AFS_ACE_READ and AFS_ACE_WRITE permission bits should not
be used to make access decisions for the directory itself.  They
are meant to control access for the objects contained in that
directory.

Reading a directory is allowed if the AFS_ACE_LOOKUP bit is set.
This would cause an incorrect access denied error for a directory
with AFS_ACE_LOOKUP but not AFS_ACE_READ.

The AFS_ACE_WRITE bit does not allow operations that modify the
directory.  For a directory with AFS_ACE_WRITE but neither
AFS_ACE_INSERT nor AFS_ACE_DELETE, this would result in trying
operations that would ultimately be denied by the server.

f991af3daa mqueue: fix a use-after-free in sys_mq_notify()
The retry logic for netlink_attachskb() inside sys_mq_notify()
is nasty and vulnerable:

1) The sock refcnt is already released when retry is needed
2) The fd is controllable by user-space because we already
   release the file refcnt

so we when retry but the fd has been just closed by user-space
during this small window, we end up calling netlink_detachskb()
on the error path which releases the sock again, later when
the user-space closes this socket a use-after-free could be
triggered.

Setting 'sock' to NULL here should be sufficient to fix it.

bc2c6421cb The first major feature for ext4 this merge window is the largedir
feature, which allows ext4 directories to support over 2 billion
 directory entries (assuming ~64 byte file names; in practice, users
 will run into practical performance limits first.)  This feature was
 originally written by the Lustre team, and credit goes to Artem
 Blagodarenko from Seagate for getting this feature upstream.
 
 The second major major feature allows ext4 to support extended
 attribute values up to 64k.  This feature was also originally from
 Lustre, and has been enhanced by Tahsin Erdogan from Google with a
 deduplication feature so that if multiple files have the same xattr

0abd675e97 f2fs: support plain user/group quota
This patch adds to support plain user/group quota.

Change Note by Jaegeuk Kim.

- Use f2fs page cache for quota files in order to consider garbage collection.
  so, quota files are not tolerable for sudden power-cuts, so user needs to do
  quotacheck.

- setattr() calls dquot_transfer which will transfer inode->i_blocks.
  We can't reclaim that during f2fs_evict_inode(). So, we need to count
  node blocks as well in order to match i_blocks with dquot's space.

  Note that, Chao wrote a patch to count inode->i_blocks without inode block.
  (f2fs: don't count inode block in in-memory inode.i_blocks)

- in f2fs_remount, we need to make RW in prior to dquot_resume.

- handle fault_injection case during f2fs_quota_off_umount

- TODO: Project quota

eef914a9eb [SMB3] Improve security, move default dialect to SMB3 from old CIFS
Due to recent publicity about security vulnerabilities in the
much older CIFS dialect, move the default dialect to the
widely accepted (and quite secure) SMB3.0 dialect from the
old default of the CIFS dialect.

We do not want to be encouraging use of less secure dialects,
and both Microsoft and CERT now strongly recommend not using the
older CIFS dialect (SMB Security Best Practices
"recommends disabling SMBv1").

SMB3 is both secure and widely available: in Windows 8 and later,
Samba and Macs.

Users can still choose to explicitly mount with the less secure
dialect (for old servers) by choosing "vers=1.0" on the cifs
mount

2a38e12053 [SMB3] Remove ifdef since SMB3 (and later) now STRONGLY preferred
Remove the CONFIG_CIFS_SMB2 ifdef and Kconfig option since they
must always be on now.

For various security reasons, SMB3 and later are STRONGLY preferred
over CIFS and older dialects, and SMB3 (and later) will now be
the default dialects so we do not want to allow them to be
ifdeffed out.

In the longer term, we may be able to make older CIFS support
disableable in Kconfig with a new set of #ifdef, but we always
want SMB3 and later support enabled.

511c54a2f6 CIFS: Reconnect expired SMB sessions
According to the MS-SMB2 spec (3.2.5.1.6) once the client receives
STATUS_NETWORK_SESSION_EXPIRED error code from a server it should
reconnect the current SMB session. Currently the client doesn't do
that. This can result in subsequent client requests failing by
the server. The patch adds an additional logic to the demultiplex
thread to identify expired sessions and reconnect them.

8b6b3172ce Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:
 "Mostly fixing some light fallout from the changes that went into the
  merge window.

   1) Fix memory leaks on network namespace teardown in netfilter, from
      Liping Zhang.

   2) When comparing ipv6 nexthops, we have to take the lightweight
      tunnel state into account as well. From David Ahern.

   3) Fix socket option object length check in the new TLS code, from
      Matthias Rosenfelder.

   4) Fix memory leak in nfp driver flower support, from Jakub Kicinski.

   5) Several netlink attribute validation fixes in cfg80211, from
      Srinivas Dasari.

   6) Fix context array leak in virtio_net, from Jason Wang.

   7) SKB use after free in hns driver, from Yusheng Lin.

   8) Fix socket leak on accept() in RDS, from Sowmini Varadhan. Also
      add a WARN_ON() to sock_graft() so other protocol stacks don't
      trip over this as well"

634a816095 fix waitid(2) breakage
We lose the distinction between "found a PID" and "nothing, but that's not
an error" a bit too early in waitid().  Easily fixed, fortunately...

e8df760307 net: ethernet: mediatek: remove useless code in mtk_probe()
Remove useless local variables _match_, _soc_ and the code related.

Notice that

const struct of_device_id of_mtk_match[] = {
        { .compatible = "mediatek,mt2701-eth" },
        {},
};

So match->data is NULL.
