The patch titled
quicklists: Only consider memory that can be used with GFP_KERNEL
has been removed from the -mm tree. Its filename was
quicklists-only-consider-memory-that-can-be-used-with-gfp_kernel.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: quicklists: Only consider memory that can be used with GFP_KERNEL
From: Christoph Lameter <clameter@xxxxxxx>
Quicklists calculates the size of the quicklists based on the number of
free pages. This must be the number of free pages that can be allocated
with GFP_KERNEL. node_page_state() includes the pages in ZONE_HIGHMEM and
ZONE_MOVABLE which may lead the quicklists to become too large causing OOM.
