btw., updated patch is below - the right order is to first do
debug_locks_off(), then debug_locks_silent.
[ btw., could you fix your mailer so that a reply to your mails doesnt
put all participants into the 'To:' line? You can do it via adding
"unset followup_to" to your $HOME/.muttrc file. ]

Subject: [patch] lock debugging: fix DEBUG_LOCKS_WARN_ON() & debug_locks_silent
From: Ingo Molnar <[EMAIL PROTECTED]>
Matthew Wilcox noticed that the debug_locks_silent use should be
inverted in DEBUG_LOCKS_WARN_ON(). This bug was causing spurious
stacktraces and incorrect failures in the locking self-test on the
parisc kernel.
