From 8759ec50a6cad7ca5a6d63e657d25b85ab5ba44a Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Wed, 26 Nov 2008 10:01:31 +0200 Subject: [PATCH] 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.
