[PATCH] Introduce generic_file_splice_write_nolock()
This allows file systems to manage their own i_mutex locking while still re-using the generic_file_splice_write() logic. OCFS2 in particular wants this so that it can order cluster locks within i_mutex. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
