[PULL REQUEST] O_SYNC cleanup series

[PULL REQUEST] O_SYNC cleanup series

[Jan Kara]

  Hello Linus,

  could you please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs-2.6.git osync_cleanup

  to get a patch series that cleans up handling of O_SYNC open flag. After
this patch series, it uses the same code as standard fsync / fdatasync.
  The patch series contains:

Christoph Hellwig (2):
      vfs: Rename generic_file_aio_write_nolock
      fsync: wait for data writeout completion before calling ->fsync

Jan Kara (15):
      vfs: Introduce filemap_fdatawait_range
      vfs: Export __generic_file_aio_write() and add some comments
      vfs: Remove syncing from generic_file_direct_write() and generic_file_buffered_write()
      pohmelfs: Use __generic_file_aio_write instead of generic_file_aio_write_nolock
      ocfs2: Use __generic_file_aio_write instead of generic_file_aio_write_nolock
      vfs: Introduce new helpers for syncing after writing to O_SYNC file or IS_SYNC inode
      ext2: Update comment about generic_osync_inode
      ext3: Remove syncing logic from ext3_file_write
      ext4: Remove syncing logic from ext4_file_write
      ntfs: Use new syncing helpers and update comments
      ocfs2: Update syncing after splicing to match generic version
      xfs: Convert sync_page_range() to simple filemap_write_and_wait_range()
      pohmelfs: Use new syncing helper
      fat: Opencode sync_page_range_nolock()
      vfs: Remove generic_osync_inode() and sync_page_range{_nolock}()
