[PATCH 3/4] zonefs: remove ->writepage

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



->writepage is only used for single page writeback from memory reclaim,
and not called at all for cgroup writeback.  Follow the lead of XFS
and remove ->writepage and rely entirely on ->writepages.
