Merge tag 'for-5.1-part1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba: "This contains usual mix of new features, core changes and fixes; full list below. I'm planning second pull request, with a few more fixes that arrived recently but too close to merge window, will send it next week. New features: - support zstd compression levels - new ioctl to unregister a device from the module (ie. reverse of device scan) - scrub prints a message to log when it's about to start or finish Core changes: - qgroups can now skip part of a tree that does not get updated during relocation, because this does not affect the quota accounting, estimated speedup in run time is about 20% - the compression workspace management had to be enhanced due to zstd requirements - various enospc fixes, when there's high fragmentation the over-reservation can cause ENOSPC that might not happen after a flush, in such cases try to wait if the situation improves Fixes: - various ioctls could overwrite previous return value if copy_to_user fails, fix this so the original error is reported - more reclaim vs GFP_KERNEL fixes - other cleanups and refactoring - fix a (valid) lockdep warning in a test when device replace is destroying worker threads - make qgroup async transaction commit more aggressive, this avoids some 'quota limit reached' errors if there are not enough data to trigger transaction in order to flush - fix deadlock between snapshot deletion and quotas when backref walking is called from context that already holds the same locks - fsync fixes: - fix fsync after succession of renames of different files - fix fsync after succession of renames and unlink/rmdir" * tag 'for-5.1-part1-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (92 commits) btrfs: Remove unnecessary casts in btrfs_read_root_item Btrfs: remove assertion when searching for a key in a node/leaf Btrfs: add missing error handling after doing leaf/node binary search btrfs: drop the lock on error in btrfs_dev_replace_cancel btrfs: ensure that a DUP or RAID1 block group has exactly two stripes btrfs: init csum_list before possible free Btrfs: remove no longer needed range length checks for deduplication Btrfs: fix fsync after succession of renames and unlink/rmdir Btrfs: fix fsync after succession of renames of different files btrfs: honor path->skip_locking in backref code btrfs: qgroup: Make qgroup async transaction commit more aggressive btrfs: qgroup: Move reserved data accounting from btrfs_delayed_ref_head to btrfs_qgroup_extent_record btrfs: scrub: remove unused nocow worker pointer btrfs: scrub: add assertions for worker pointers btrfs: scrub: convert scrub_workers_refcnt to refcount_t btrfs: scrub: add scrub_lock lockdep check in scrub_workers_get btrfs: scrub: fix circular locking dependency warning btrfs: fix comment its device list mutex not volume lock btrfs: extent_io: Kill the forward declaration of flush_write_bio btrfs: Fix grossly misleading argument names in extent io search ...
