Just out of interest, do you have CONFIG_AUDIT_SYSCALL enabled? Does it go
away if you disable it?
Also, what filesystems do you use? And if you run
while : ; do cat /proc/slabinfo | grep names_cache ; sleep 2; done
in one terminal, can you see if you can find any correlation to some
particular action or behaviour that would seem to be part of leaking it?
It really shouldn't grow very big at all normally. Ie the counts are
normally something like a few tens of entries used or whatever - all the
allocations should basically be temporary, and your 200+ _thousand_
entries are way out of line.
If you can't find anything obvious, then we can try to figure out a way to
just print out the contents of your name entries, I bet that would give a
clue about who is allocating them. But there's also been various leak
debugging patches out there that may help. Manfred may have pointers.
