Hi Linus,
Here are the XFS changes for 4.12. The big new feature for this release
is the new space mapping ioctl that we've been discussing since LSF2016,
but other than that most of the patches are larger bug fixes, memory
corruption prevention, and other cleanups. I tried a test merge against
HEAD about 15 minutes ago and it committed cleanly, so I don't
anticipate any problems. Let me know if you encounter any problems.
