Grrr. Wonder why it's skipping stuff ...

proc_root_lookup() is definied in fs/proc/root.c
proc_lookup() is defined in fs/proc/generic.c
proc_pid_lookup() is defined in fs/proc/base.c

But as we have .text.lock.base ... doesn't that mean that the guilty
party is proc_pid_lookup() ? In which case, maybe wli's favourite
tasklist_lock is the guilty party here?

OK ... well tried stage 1 at least. New trace output below, and I'll try
to do something more useful with it this time ;-) I've hacked out the
boring bits, so it'll fit under the lkml size limit. I presume this was
the one you were referring to last time:

ps            R 00000060 4263132092 31912  31675         31919       (NOTLB)
Call Trace:

So presumably this time it's:

I suspect that's bugger all use to man or beast though.
