As of 2.6.31 it's clear __GFP_NOFAIL should no longer be used and it may disappear from the kernel at any time. To handle this I have simply added *_nofail wrappers in the kmem implementation which perform the retry for non-atomic allocations. From linux-2.6.31 mm/page_alloc.c:1166 /* * __GFP_NOFAIL is not to be used in new code. * * All __GFP_NOFAIL callers should be fixed so that they * properly detect and handle allocation failures. * * We most definitely don't want callers attempting to * allocate greater than order-1 page units with * __GFP_NOFAIL. */ WARN_ON_ONCE(order > 1);
