This patchset touches at least the dax, pagecache, and xfs subsystems. Assuming it's too late for 5.19, how should we stage this for 5.20? I could just add the entire series to iomap-5.20-merge and base the xfs-5.20-merge off of that? But I'm not sure what else might be landing in the other subsystems, so I'm open to input. --D > xfs: Implement ->notify_failure() for XFS > fsdax: set a CoW flag when associate reflink mappings > fsdax-reflink: > fsdax: Output address in dax_iomap_pfn() and rename it > fsdax: Introduce dax_iomap_cow_copy() > fsdax: Replace mmap entry in case of CoW > fsdax: Add dax_iomap_cow_copy() for dax zero > fsdax: Dedup file range to use a compare function > xfs: support CoW in fsdax mode > xfs: Add dax dedupe support > > drivers/dax/super.c | 67 +++++- > drivers/md/dm.c | 2 +- > drivers/nvdimm/pmem.c | 17 ++ > fs/dax.c | 398 ++++++++++++++++++++++++++++++------ > fs/erofs/super.c | 13 +- > fs/ext2/super.c | 7 +- > fs/ext4/super.c | 9 +- > fs/remap_range.c | 31 ++- > fs/xfs/Makefile | 5 + > fs/xfs/xfs_buf.c | 10 +- > fs/xfs/xfs_file.c | 9 +- > fs/xfs/xfs_fsops.c | 3 + > fs/xfs/xfs_inode.c | 69 ++++++- > fs/xfs/xfs_inode.h | 1 + > fs/xfs/xfs_iomap.c | 46 ++++- > fs/xfs/xfs_iomap.h | 3 + > fs/xfs/xfs_mount.h | 1 + > fs/xfs/xfs_notify_failure.c | 220 ++++++++++++++++++++ > fs/xfs/xfs_reflink.c | 12 +- > fs/xfs/xfs_super.h | 1 + > include/linux/dax.h | 56 ++++- > include/linux/fs.h | 12 +- > include/linux/memremap.h | 12 ++ > include/linux/mm.h | 2 + > include/linux/page-flags.h | 6 + > mm/memory-failure.c | 257 ++++++++++++++++------- > 26 files changed, 1087 insertions(+), 182 deletions(-) > create mode 100644 fs/xfs/xfs_notify_failure.c > > -- > 2.35.1 > > >
