slab: remove GFP_THISNODE clearing from alloc_slabmgmt()
Commit 6cb062296f73e74768cca2f3eaf90deac54de02d ("Categorize GFP flags") left one call-site in alloc_slabmgmt() to clear GFP_THISNODE instead of GFP_CONSTRAINT_MASK. Unfortunately, that ends up clearing __GFP_NOWARN and __GFP_NORETRY as well which is not what we want. As the only caller of alloc_slabmgmt() already clears GFP_CONSTRAINT_MASK before passing local_flags to it, we can just remove the clearing of GFP_THISNODE. This patch should fix spurious page allocation failure warnings on the mempool_alloc() path. See the following URL for the original discussion of the bug: http://lkml.org/lkml/2008/10/27/100 Acked-by: Christoph Lameter <cl@linux-foundation.org> Reported-by: Miklos Szeredi <miklos@szeredi.hu> Signed-off-by: Pekka Enberg <penberg@cs.helsinki.fi>
