Christoph,
While going through the slab code, I observed that alien caches are
not getting resized, when user changes the slab tunables. Appended patch
tries to fix this. Please review and let me know if I missed anything.
thanks,
suresh

Resize the alien caches too based on the slab tunables.

Christoph already rejected the patch, but I have one further comment :
l3->alien should be fetched after spin_lock_irq() of course.
It's true that the :
if (limit > 1) limit = 12;
from alloc_alien_cache() is quite disturbing and could be cleaned up.
