From e72e9c23ee025a4c063ca112ba0a6059f9ecc9b7 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Thu, 27 Mar 2008 20:56:33 -0700 Subject: [PATCH] Revert "SLUB: remove useless masking of GFP_ZERO" This reverts commit 3811dbf67162bd08412f1b0e02e554f353e93bdb. The masking was not at all useless, and it was sensible. We handle GFP_ZERO in the caller, and passing it down to any page allocator logic is buggy and wrong.
