Hi Al, Linus, I *think* the attached patch is needed with the new mount API. David --- mqueue: Fix bug from mount API conversion Fix a possible bug from the mount API conversion of the mqueue filesystem whereby mq_init_ns() passes the root IPC namespace to mq_create_mount() rather than the namespace passed in. I don't know if this is the bug Eric is reporting since he didn't give any details. Reported-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David Howells <dhowells@redhat.com> ---
