[GIT PULL] iomap: new code for 6.3

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

 



Hi Linus,

Please pull this branch with changes for iomap for 6.3-rc1.  This is
mostly rearranging things to make life easier for gfs2, nothing all that
mindblowing for this release.

As usual, I did a test-merge with the main upstream branch as of a few
minutes ago, and didn't see any conflicts.  Please let me know if you
encounter any problems.

iomap: Rename page_ops to folio_ops (2023-01-18 10:44:05 -0800)

----------------------------------------------------------------
New code for 6.3:

- Change when the iomap page_done function is called so that we still
have a locked folio in the success case.  This fixes a writeback race
in gfs2.
- Change when the iomap page_prepare function is called so that gfs2
can recover from OOM scenarios more gracefully.
- Rename the iomap page_ops to folio_ops, since they operate on folios
now.
