This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Vladimir Davydov <vdavydov@xxxxxxxxxxxxx>
Subject: mm: vmscan: respect NUMA policy mask when shrinking slab on direct reclaim
When direct reclaim is executed by a process bound to a set of NUMA nodes,
we should scan only those nodes when possible, but currently we will scan
kmem from all online nodes even if the kmem shrinker is NUMA aware. That
said, binding a process to a particular NUMA node won't prevent it from
shrinking inode/dentry caches from other nodes, which is not good. Fix
this.
