[GIT PULL] xfs: updates for 4.10-rc1

From: Dave Chinner
Date: Wed Dec 14 2016 - 23:16:50 EST

Hi Linus,

Can you please pull the XFS update from the tag below? There is
quite a varied bunch of stuff in this update, and some of it
you will have already merged through the ext4 tree which imported
the dax-4.10-iomap-pmd topic branch from the XFS tree.

There is also a new direct IO implementation that uses the iomap
infrastructure. It's much simpler, faster, and has lower IO latency
than the existing direct IO infrastructure. However, there were
dependencies on the block tree and dax-4.10-iomap-pmd changes (both
of which you've already merged) so there's some merge issues that
you need to be aware of. The linux-next patch from Stephen here:

https://lkml.org/lkml/2016/12/13/755

addresses the block tree merge issues, whilst the resolution of the
include/linux/iomap.h conflict for the IOMAP_DIRECT flag addition
is obvious.

In other news you need to know about, this is likely the last pull
request you'll see from me for some time. I'm about to go on
extended leave at xmas time and won't be back until July next year.
While I'm gone, Darrick is going to be taking over the job of
feeding the XFS kernel tree and sending you pull requests. The
location of the XFS tree will also change - I've already set up a
new tree at fs/xfs/xfs-linux on kernel.org. Once everything for this
merge window is sorted out, we'll get linux-next pointed at the new
tree and all future will be done against that tree.

Darrick is currently planning to send you a MAINTAINER file update
pull request some time around -rc3/-rc4 to make sure he's familiar
with the process before the next merge window rolls around.

-Dave.

xfs: updates for 4.10-rc1

Contained in this update:
- DAX PMD vaults via iomap infrastructure
- Direct-io support in iomap infrastructure
- removal of now-redundant XFS inode iolock, replaced with VFS i_rwsem
- synchronisation with fixes and changes in userspace libxfs code
- extent tree lookup helpers
- lots of little corruption detection improvements to verifiers
- optimised CRC calculations
- faster buffer cache lookups
- deprecation of barrier/nobarrier mount options - we always use
REQ_FUA/REQ_FLUSH where appropriate for data integrity now
- cleanups to speculative preallocation
- miscellaneous minor bug fixes and cleanups
