The patch titled
SLUB: Rename NUMA defrag_ratio to remote_node_defrag_ratio
has been removed from the -mm tree. Its filename was
slub-rename-numa-defrag_ratio-to-remote_node_defrag_ratio.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: SLUB: Rename NUMA defrag_ratio to remote_node_defrag_ratio
From: Christoph Lameter <[EMAIL PROTECTED]>
The NUMA defrag works by allocating objects from partial slabs on remote
nodes. Rename it to
remote_node_defrag_ratio
to be clear about this.
