Pull btrfs updates from David Sterba: "Highlights: - speedup dead root detection during orphan cleanup, eg. when there are many deleted subvolumes waiting to be cleaned, the trees are now looked up in radix tree instead of a O(N^2) search - snapshot creation with inherited qgroup will mark the qgroup inconsistent, requires a rescan - send will emit file capabilities after chown, this produces a stream that does not need postprocessing to set the capabilities again - direct io ported to iomap infrastructure, cleaned up and simplified code, notably removing last use of struct buffer_head in btrfs code Core changes: - factor out backreference iteration, to be used by ordinary backreferences and relocation code - improved global block reserve utilization * better logic to serialize requests * increased maximum available for unlink * improved handling on large pages (64K) - direct io cleanups and fixes * simplify layering, where cloned bios were unnecessarily created for some cases * error handling fixes (submit, endio) * remove repair worker thread, used to avoid deadlocks during repair - refactored block group reading code, preparatory work for new type of block group storage that should improve mount time on large filesystems Cleanups: - cleaned up (and slightly sped up) set/get helpers for metadata data structure members - root bit REF_COWS got renamed to SHAREABLE to reflect the that the blocks of the tree get shared either among subvolumes or with the relocation trees Fixes: - when subvolume deletion fails due to ENOSPC, the filesystem is not turned read-only - device scan deals with devices from other filesystems that changed ownership due to overwrite (mkfs) - fix a race between scrub and block group removal/allocation - fix long standing bug of a runaway balance operation, printing the same line to the syslog, caused by a stale status bit on a reloc tree that prevented progress - fix corrupt log due to concurrent fsync of inodes with shared extents - fix space underflow for NODATACOW and buffered writes when it for some reason needs to fallback to COW mode" * tag 'for-5.8-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (133 commits) btrfs: fix space_info bytes_may_use underflow during space cache writeout btrfs: fix space_info bytes_may_use underflow after nocow buffered write btrfs: fix wrong file range cleanup after an error filling dealloc range btrfs: remove redundant local variable in read_block_for_search btrfs: open code key_search btrfs: split btrfs_direct_IO to read and write part btrfs: remove BTRFS_INODE_READDIO_NEED_LOCK fs: remove dio_end_io() btrfs: switch to iomap_dio_rw() for dio iomap: remove lockdep_assert_held() iomap: add a filesystem hook for direct I/O bio submission fs: export generic_file_buffered_read() btrfs: turn space cache writeout failure messages into debug messages btrfs: include error on messages about failure to write space/inode caches btrfs: remove useless 'fail_unlock' label from btrfs_csum_file_blocks() btrfs: do not ignore error from btrfs_next_leaf() when inserting checksums btrfs: make checksum item extension more efficient btrfs: fix corrupt log due to concurrent fsync of inodes with shared extents btrfs: unexport btrfs_compress_set_level() btrfs: simplify iget helpers ...
