+Subject: ocfs2: update seq_file index in ocfs2_dlm_seq_next
+
+From: Wengang Wang <wen.gang.wang@oracle.com>
+
+commit 914eec5e980171bc128e7e24f7a22aa1d803570e upstream.
+
+The following INFO level message was seen:
+
+seq_file: buggy .next function ocfs2_dlm_seq_next [ocfs2] did not
+update position index
+
+Fix:
+Update *pos (so m->index) to make seq_read_iter happy though the index its
+self makes no sense to ocfs2_dlm_seq_next.
