This is an updated proposal for changing the iomap page_ops operations
to make them more flexible so that they better suite the filesystem
needs. It closes a race on gfs2 and cleans up the recent iomap changes
merged in the following upstream commit:
87be949912ee ("Merge tag 'xfs-6.2-merge-8' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux")
The first patch introduces a folio_may_straddle_isize() helper as a
replacement for pagecache_isize_extended() when we have a locked folio.
This still needs independent verification, but it looks like a
worthwhile improvement to me. I've left it in this patch queue for now,
but I can moved out of the way if prefered.
Any thoughts?
Thanks,
Andreas
