From 469340236a7c9673df3e6a2425f559517f01464e Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Wed, 11 Oct 2006 01:21:26 -0700 Subject: [PATCH] mm: kevent threads: use MPOL_DEFAULT Switch the memory policy of the kevent threads to MPOL_DEFAULT while leaving the kzalloc of the workqueue structure on interleave. This means that all code executed in the context of the kevent thread is allocating node local.
