Besides introducing additional seeks, this also can lead to extreme file fragmentation on zoned devices when a lot of files are cached relative to the available writeback bandwidth. Add a superblock field that allows the file system to override the default size, and set it to the zone size for zoned XFS. * patches from https://patch.msgid.link/20251017034611.651385-1-hch@lst.de: xfs: set s_min_writeback_pages for zoned file systems writeback: allow the file system to override MIN_WRITEBACK_PAGES writeback: cleanup writeback_chunk_size Link: https://patch.msgid.link/20251017034611.651385-1-hch@lst.de Signed-off-by: Christian Brauner --- 891bea757c771dca47e871444faecb1ed642a311
