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" * tag 'for-4.16-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (155 commits) btrfs: drop devid as device_list_add() arg btrfs: get device pointer from device_list_add() btrfs: set the total_devices in device_list_add() btrfs: move pr_info into device_list_add btrfs: make btrfs_free_stale_devices() to match the path btrfs: rename btrfs_free_stale_devices() arg to skip_dev btrfs: make btrfs_free_stale_devices() argument optional btrfs: make btrfs_free_stale_device() to iterate all stales btrfs: no need to check for btrfs_fs_devices::seeding btrfs: Use IS_ALIGNED in btrfs_truncate_block instead of opencoding it Btrfs: noinline merge_extent_mapping Btrfs: add WARN_ONCE to detect unexpected error from merge_extent_mapping Btrfs: extent map selftest: dio write vs dio read Btrfs: extent map selftest: buffered write vs dio read Btrfs: add extent map selftests Btrfs: move extent map specific code to extent_map.c Btrfs: add helper for em merge logic Btrfs: fix unexpected EEXIST from btrfs_get_extent Btrfs: fix incorrect block_len in merge_extent_mapping btrfs: Remove unused readahead spinlock ...
