Unfortunately, I forgot to add slub_debug option and build kmemleak so wasn't able to look at this case further, and when I rebooted with these enabled/built, it was secpath_cache again. So previously noted "slabtop showed 'kmalloc-64' being the 99% offender in the past, but with recent kernels (3.6.1), it has changed to 'secpath_cache'" seem to be incorrect, as it seem to depend not on kernel version, but some other factor. Guess I'll try to reboot a few more times to see if I can catch kmalloc-64 leaking (instead of secpath_cache) again. -- Mike Kazantsev // fraggod.net
