Subject: SLUB: add checks for interrupts disabled
From: Christoph Lameter <clameter@xxxxxxx>
This only adds interrupt disabled checks to code paths taken if debugging
is on. I want to avoid constant checks in hot paths (like in SLAB).
VM_BUG_ON may be enabled by distributors who want to play it safe.
