ocfs2: fix i_mutex locking in ocfs2_splice_to_file()
Rearrange locking of i_mutex on destination and call to ocfs2_rw_lock() so locks are only held while buffers are copied with the pipe_to_file() actor, and not while waiting for more data on the pipe. Signed-off-by: Miklos Szeredi <mszeredi@suse.cz> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
