- have-kswapd-keep-a-minimum-order-free-other-than-order-0-fix.patch removed from -mm tree

[akpm@linux-foundation.org]

The patch titled
     have-kswapd-keep-a-minimum-order-free-other-than-order-0 fix
has been removed from the -mm tree.  Its filename was
     have-kswapd-keep-a-minimum-order-free-other-than-order-0-fix.patch

This patch was dropped because it was folded into have-kswapd-keep-a-minimum-order-free-other-than-order-0.patch

------------------------------------------------------
Subject: have-kswapd-keep-a-minimum-order-free-other-than-order-0 fix
From: Christoph Lameter <clameter@sgi.com>

On third thought: The trouble with this solution is that we will now set
the order to that used by the largest kmalloc cache.  Bad...  this could be
6 on i386 to 13 if CONFIG_LARGE_ALLOCs is set.  The large kmalloc caches
are rarely used and we are used to OOMing if those are utilized to
frequently.

I guess we should only set this for non kmalloc caches then.  So move the
call into kmem_cache_create?  Would make the min order 3 on most of my mm
machines.
