John Garry 9e0933c21c fs: iomap: Atomic write support
Support direct I/O atomic writes by producing a single bio with REQ_ATOMIC
flag set.

Initially FSes (XFS) should only support writing a single FS block
atomically.

As with any atomic write, we should produce a single bio which covers the
complete write length.
