Hi Linus,
Can you please pull the XFS update from the tag below? You will get
a merge conflict against fs/xfs/xfs_ioctl.c - I committed "xfs: fix
type confusion in xfs_ioc_swapext" with an additional comment to
explain why such a unique test was being done in the ioctl code.
As for the rest of the changes, the major addition is the new iomap
based block mapping infrastructure. We've been kicking this about
locally for years, but there are other filesystems want to use it
too (e.g. gfs2). Now it is fully working, reviewed and ready for
merge and be used by other filesystems. There are a lot of other
fixes and cleanups in the tree, but those are XFS internal things
and none are of the scale or visibility of the iomap changes. See
the tag description below for details.
I am likely to send another pull request next week - we're ijust
about ready to merge some new functionality (on disk block->owner
reverse mapping infrastructure), but that's a huge chunk of code (74
files changed, 7283 insertions(+), 1114 deletions(-)) so I'm keeping
that separate to all the "normal" pull request changes so they don't
get lost in the noise.
-Dave.

----------------------------------------------------------------
xfs: update for 4.8-rc1
Changes in this update:
o generic iomap based IO path infrastructure
o generic iomap based fiemap implementation
o xfs iomap based Io path implementation
o buffer error handling fixes
o tracking of in flight buffer IO for unmount serialisation
o direct IO and DAX io path separation and simplification
o shortform directory format definition changes for wider platform compatibility
o various buffer cache fixes
o cleanups in preparation for rmap merge
o error injection cleanups and fixes
o log item format buffer memory allocation restructuring to prevent rare OOM
reclaim deadlocks
o sparse inode chunks are now fully supported.
