David Howells 46ed60dcd4 netfs: Implement unbuffered/DIO vs buffered I/O locking 
Borrow NFS's direct-vs-buffered I/O locking into netfslib.  Similar code is
also used in ceph.

Modify it to have the correct checker annotations for i_rwsem lock
acquisition/release and to return -ERESTARTSYS if waits are interrupted.
