From 6eb27e1fdf5781719a3d2e90e6c89fa012135c62 Mon Sep 17 00:00:00 2001 From: Bob Liu Date: Mon, 24 May 2010 14:32:00 -0700 Subject: [PATCH] mempolicy: remove case MPOL_INTERLEAVE from policy_zonelist() In policy_zonelist() mode MPOL_INTERLEAVE shouldn't happen, so fall through to BUG() instead of break to return. I also fixed the comment.
