The patch titled
Slab GFP_ZERO support: Use obj_size instead of buffer_size.
has been removed from the -mm tree. Its filename was
slab-allocators-support-__gfp_zero-in-all-allocators-fix.patch
This patch was dropped because it was folded into slab-allocators-support-__gfp_zero-in-all-allocators.patch
------------------------------------------------------
Subject: Slab GFP_ZERO support: Use obj_size instead of buffer_size.
From: Christoph Lameter <clameter@xxxxxxx>
Buffer size includes the metadata in the debug case so we were clearing
SLAB metadata. The obj_size() function determines the size independent of
CONFIG_SLAB_DEBUG.
