WARNING: at lib/kref.c:33 kref_get() (-mm 2007-11-06-02-32++)

[Erez Zadok]

Setup: FC6 system with MM snapshot broken-out-2007-11-06-02-32 and these two
patches added:

r-o-bind-mounts-track-number-of-mount-writer-fix-buggy-loop.patch
r-o-bind-mounts-track-number-of-mount-writer-fix-buggy-loop-checkpatch-fixes.patch

Booting the machine, waiting a few minutes (not logging in or doing anything
else).  I get:

 =======================

There's no other indication where the setuid(2) came from, perhaps cron?
