Subject: SLUB: reduce antifrag max order
From: Christoph Lameter <clameter@xxxxxxx>
My test systems fails to obtain order 4 allocs after prolonged use. So the
Antifragmentation patches are unable to guarantee order 4 blocks after a while
(straight compile, edit load).
Reduce the the max order if antifrag measures are detected to 3.
