If creds are allocated in nfsd_setuser() and never freed? groups_alloc()
can also explain size-256 slab grew, so this may be the place where
things are allocated, but why they are not freed?
This may also explain why I did not see this for the large sequential
IO, since number of requests to the server was noticebly smaller, than
in random IO test.
