Merge tag 'for-4.16-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"Features or user visible changes:
- fallocate: implement zero range mode
- avoid losing data raid profile when deleting a device
- tree item checker: more checks for directory items and xattrs
Notable fixes:
- raid56 recovery: don't use cached stripes, that could be
potentially changed and a later RMW or recovery would lead to
corruptions or failures
- let raid56 try harder to rebuild damaged data, reading from all
stripes if necessary
- fix scrub to repair raid56 in a similar way as in the case above
Other:
- cleanups: device freeing, removed some call indirections, redundant
bio_put/_get, unused parameters, refactorings and renames
- RCU list traversal fixups
- simplify mount callchain, remove recursing back when mounting a
subvolume
- plug for fsync, may improve bio merging on multiple devices
- compression heurisic: replace heap sort with radix sort, gains some
performance
- add extent map selftests, buffered write vs dio"
