Hi folks,

The for-next branch of the xfs kernel repository at

git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs.git

has just been updated. This update includes the long-awaited
iomap-based IO path infrastructure changes that Christoph has
finished off, along with a few bug fixes and the first handful of
miscellaneous changes from Darrick's mega-rmap patchset.

The iomap infrastructure patches are in their own separate branch -
fs-4.8-iomap-infrastructure - so it can be considered a stable
branch and hence can be merged into other fs trees so they can start
adding their own iomap-based work.  It will be included in the
linux-next build by the merge into the XFS tree's for-next branch.
Any bug fixes that are needed will be appended to this branch, so
please cc me on bug reports so I see them quickly.

Cheers,

Dave.

The new head of the for-next branch is commit:
