Merge branch 'for-4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba: "There are some new user features and the usual load of invisible enhancements or cleanups. New features: - extend mount options to specify zlib compression level, -o compress=zlib:9 - v2 of ioctl "extent to inode mapping", addressing a usecase where we want to retrieve more but inaccurate results and do the postprocessing in userspace, aiding defragmentation or deduplication tools - populate compression heuristics logic, do data sampling and try to guess compressibility by: looking for repeated patterns, counting unique byte values and distribution, calculating Shannon entropy; this will need more benchmarking and possibly fine tuning, but the base should be good enough - enable indexing for btrfs as lower filesystem in overlayfs - speedup page cache readahead during send on large files Internal enhancements: - more sanity checks of b-tree items when reading them from disk - more EINVAL/EUCLEAN fixups, missing BLK_STS_* conversion, other errno or error handling fixes - remove some homegrown IO-related logic, that's been obsoleted by core block layer changes (batching, plug/unplug, own counters) - add ref-verify, optional debugging feature to verify extent reference accounting - simplify code handling outstanding extents, make it more clear where and how the accounting is done - make delalloc reservations per-inode, simplify the code and make the logic more straightforward - extensive cleanup of delayed refs code Notable fixes: - fix send ioctl on 32bit with 64bit kernel" * 'for-4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (102 commits) btrfs: Fix bug for misused dev_t when lookup in dev state hash table. Btrfs: heuristic: add Shannon entropy calculation Btrfs: heuristic: add byte core set calculation Btrfs: heuristic: add byte set calculation Btrfs: heuristic: add detection of repeated data patterns Btrfs: heuristic: implement sampling logic Btrfs: heuristic: add bucket and sample counters and other defines Btrfs: compression: separate heuristic/compression workspaces btrfs: move btrfs_truncate_block out of trans handle btrfs: don't call btrfs_start_delalloc_roots in flushoncommit btrfs: track refs in a rb_tree instead of a list btrfs: add a comp_refs() helper btrfs: switch args for comp_*_refs btrfs: make the delalloc block rsv per inode btrfs: add tracepoints for outstanding extents mods Btrfs: rework outstanding_extents btrfs: increase output size for LOGICAL_INO_V2 ioctl btrfs: add a flags argument to LOGICAL_INO and call it LOGICAL_INO_V2 btrfs: add a flag to iterate_inodes_from_logical to find all extent refs for uncompressed extents btrfs: send: remove unused code ...
