Subject: SLUB slab validation: Alloc while interrupts are disabled must use GFP_ATOMIC
X-Git-Tag: v2.6.22-rc5~19
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=dd08c40e3e23f868eb0e49f638eb208736ec7e66;p=linux-2.6-omap-h63xx.git

SLUB slab validation: Alloc while interrupts are disabled must use GFP_ATOMIC

The data structure to manage the information gathered about functions
allocating and freeing objects is allocated when the list_lock has already
been taken.  We need to allocate with GFP_ATOMIC instead of GFP_KERNEL.
