Merge branch 'work.read_write' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

Pull read/write fix from Al Viro:
 "file_start_write()/file_end_write() got mixed into vfs_iter_write() by
  accident; that's a deadlock for all existing callers - they already do
  that, some - quite a bit outside.

  Easily fixed, fortunately"

* 'work.read_write' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  move file_{start,end}_write() out of do_iter_write()
