Thanks, FYI in 5.0-rc: - btrfs: wait on ordered extents on abort cleanup - btrfs: handle delayed ref head accounting cleanup in abort in misc-next: - btrfs: make btrfs_destroy_delayed_refs use btrfs_delete_ref_head - btrfs: make btrfs_destroy_delayed_refs use btrfs_delayed_ref_lock - btrfs: call btrfs_create_pending_block_groups unconditionally reworked as https://patchwork.kernel.org/patch/10784039/ : - btrfs: cleanup pending bgs on transaction abort - btrfs: just delete pending bgs if we are aborted
