Subject: ocfs2: update seq_file index in ocfs2_dlm_seq_next
Date: Tue, 19 Nov 2024 09:45:00 -0800
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.
