Merge tag 'for-5.13-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba: "The updates this time are mostly stabilization, preparation and minor improvements. User visible improvements: - readahead for send, improving run time of full send by 10% and for incremental by 25% - make reflinks respect O_SYNC, O_DSYNC and S_SYNC flags - export supported sectorsize values in sysfs (currently only page size, more once full subpage support lands) - more graceful errors and warnings on 32bit systems when logical addresses for metadata reach the limit posed by unsigned long in page::index - error: fail mount if there's a metadata block beyond the limit - error: new metadata block would be at unreachable address - warn when 5/8th of the limit is reached, for 4K page systems it's 10T, for 64K page it's 160T - zoned mode - relocated zones get reset at the end instead of discard - automatic background reclaim of zones that have 75%+ of unusable space, the threshold is tunable in sysfs Fixes: - fsync and tree mod log fixes - fix inefficient preemptive reclaim calculations - fix exhaustion of the system chunk array due to concurrent allocations - fix fallback to no compression when racing with remount - preemptive fix for dm-crypt on zoned device that does not properly advertise zoned support Core changes: - add inode lock to synchronize mmap and other block updates (eg. deduplication, fallocate, fsync) - kmap conversions to new kmap_local API - subpage support (continued) - new helpers for page state/extent buffer tracking - metadata changes now support read and write - error handling through out relocation call paths - many other cleanups and code simplifications" * tag 'for-5.13-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (112 commits) btrfs: zoned: automatically reclaim zones btrfs: rename delete_unused_bgs_mutex to reclaim_bgs_lock btrfs: zoned: reset zones of relocated block groups btrfs: more graceful errors/warnings on 32bit systems when reaching limits btrfs: zoned: fix unpaired block group unfreeze during device replace btrfs: fix race when picking most recent mod log operation for an old root btrfs: fix metadata extent leak after failure to create subvolume btrfs: handle remount to no compress during compression btrfs: zoned: fail mount if the device does not support zone append btrfs: fix race between transaction aborts and fsyncs leading to use-after-free btrfs: introduce submit_eb_subpage() to submit a subpage metadata page btrfs: make lock_extent_buffer_for_io() to be subpage compatible btrfs: introduce write_one_subpage_eb() function btrfs: introduce end_bio_subpage_eb_writepage() function btrfs: check return value of btrfs_commit_transaction in relocation btrfs: do proper error handling in merge_reloc_roots btrfs: handle extent corruption with select_one_root properly btrfs: cleanup error handling in prepare_to_merge btrfs: do not panic in __add_reloc_root btrfs: handle __add_reloc_root failures in btrfs_recover_relocation ...
