Subject: remove generic_writepages
Date: Thu, 29 Dec 2022 06:10:25 -1000	[thread overview]
Message-ID: <20221229161031.391878-1-hch@lst.de> (raw)

Hi all,

this series removes generic_writepages by open coding the current
functionality in the three remaining callers.  Besides removing some
code the main benefit is that one of the few remaining ->writepage
callers from outside the core page cache code go away.

Note that testing has been a bit limited - ntfs3 does not seem to
be supported by xfstests at all, and xfstests on ocfs2 is a complete
shit show even for the base line.
