Hi Trond,

the server's load seems to be a little bit lower with 2.6.27.6 plus
your patch, but OProfile still gives me 45% in
rpcauth_lookup_credcache(). See:

1060627 45.1474 (no location information) rpcauth_lookup_credcache
289362 12.3172 auth_generic.c:0 generic_match
31886 1.3573 page_alloc.c:0 get_page_from_freelist
23932 1.0187 (no location information) page_fault
22176 0.9440 (no location information) schedule
14613 0.6220 (no location information) __d_lookup
[...]
