Naohiro Aota 37b385c78c btrfs: zoned: fix critical section of relocation inode writeback ... commit 19ab78ca86 upstream. We use btrfs_zoned_data_reloc_{lock,unlock} to allow only one process to write out to the relocation inode. That critical section must include all the IO submission for the inode. However, flush_write_bio() in extent_writepages() is out of the critical section, causing an IO submission outside of the lock. This leads to an out of the order IO submission and fail the relocation process. Fix it by extending the critical section.
