From e5d9dc278c7f79c220e4506cc1ade2efa2ca73fd Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Thu, 3 Jan 2008 11:31:38 +0000 Subject: [PATCH] [GFS2] Allow page migration for writeback and ordered pages To improve performance on NUMA, we use the VM's standard page migration for writeback and ordered pages. Probably we could also do the same for journaled data, but that would need a careful audit of the code, so will be the subject of a later patch.
