[PATCH v20 19/32] ocfs2: Provide a splice-read stub
Provide a splice_read stub for ocfs2. This emits trace lines and does an atime lock/update before calling filemap_splice_read(). It doesn't do this for around direct_splice_read() as that will call ->read_iter(). A couple of new tracepoints are added for this purpose.
