Patch 2 has some minor tweaks based on feedback on v1 from Christoph. Patch 3 is new and fixes up some of the remaining broken iomap writepage error handling logic (also discussed in the v1 thread). Thoughts, reviews, flames appreciated. Brian v2: - Repost original XFS truncate down post-EOF zeroing fix. - Pass file offset to iomap ->discard_page() callback. - Add patch 3 to fix up iomap writepage error handling. v1: https://lore.kernel.org/linux-xfs/20201026182019.1547662-1-bfoster@redhat.com/ [1] https://lore.kernel.org/linux-xfs/20201007143509.669729-1-bfoster@redhat.com/ Brian Foster (3): xfs: flush new eof page on truncate to avoid post-eof corruption iomap: support partial page discard on writeback block mapping failure iomap: clean up writeback state logic on writepage error fs/iomap/buffered-io.c | 30 ++++++++++-------------------- fs/xfs/xfs_aops.c | 13 +++++++------ fs/xfs/xfs_iops.c | 10 ++++++++++ include/linux/iomap.h | 2 +- 4 files changed, 28 insertions(+), 27 deletions(-) -- 2.25.4
