Naohiro Aota bfd34b7876 btrfs-progs: zoned: redirty clean extent buffers ... Tree manipulating operations like merging nodes often release once-allocated tree nodes. Btrfs cleans such nodes so that pages in the node are not uselessly written out. On ZONED drives, however, such optimization blocks the following IOs as the cancellation of the write out of the freed blocks breaks the sequential write sequence expected by the device. Check if next dirty extent buffer is continuous to a previously written one. If not, it redirty extent buffers between the previous one and the next one, so that all dirty buffers are written sequentially.
