autofs4: close the races around autofs4_notify_daemon() Don't drop ->wq_mutex before calling autofs4_notify_daemon() only to regain it there. Besides being pointless, that opens a race window where autofs4_wait_release() could've come and freed wq->name.name. And do the debugging printk in the "reused an existing wq" case before dropping ->wq_mutex - the same reason... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Acked-by: Ian Kent <raven@themaw.net>
