Hi all, this series cleans up some of the generic write helper calling conventions and the page cache writeback / invalidation for direct I/O. This is a spinoff from the no-bufferhead kernel project, for which we'll want to an use iomap based buffered write path in the block layer. Changes since v3: - fix a generic_sync_file that got lost in fuse - fix fuse to call fuse_perform_write and not generic_perform_write Changes since v2: - stick to the existing behavior of returning a short write if the buffer fallback write or sync fails - bring back "fuse: use direct_write_fallback" which accidentally got lost in v2 Changes since v1: - remove current->backing_dev_info entirely - fix the pos/end calculation in direct_write_fallback - rename kiocb_invalidate_post_write to kiocb_invalidate_post_direct_write - typo fixes diffstat: block/fops.c | 18 ---- fs/btrfs/file.c | 6 - fs/ceph/file.c | 6 - fs/direct-io.c | 10 -- fs/ext4/file.c | 11 -- fs/f2fs/file.c | 3 fs/fuse/file.c | 45 ++--------- fs/gfs2/file.c | 6 - fs/iomap/buffered-io.c | 9 +- fs/iomap/direct-io.c | 88 ++++++++------------- fs/libfs.c | 41 ++++++++++ fs/nfs/file.c | 6 - fs/ntfs/file.c | 2 fs/ntfs3/file.c | 3 fs/xfs/xfs_file.c | 6 - fs/zonefs/file.c | 4 include/linux/fs.h | 7 - include/linux/pagemap.h | 4 include/linux/sched.h | 3 mm/filemap.c | 194 +++++++++++++++++++++--------------------------- 20 files changed, 194 insertions(+), 278 deletions(-)
