Hi Andrew, After merging the akpm tree, today's linux-next build (x86_64 allmodconfig) failed like this: mm/memcontrol.c:5269:12: error: 'CFTYPE_INSANE' undeclared here (not in a function) .flags = CFTYPE_INSANE, ^ Caused by commit 8fa6a8baeffc ("memcg: deprecate memory.force_empty knob") interacting with commits a8ddc8215e1a ("cgroup: distinguish the default and legacy hierarchies when handling cftypes") and 05ebb6e60f04 ("cgroup: make CFTYPE_ONLY_ON_DFL and CFTYPE_NO_ internal to cgroup core") from the cgroup tree. I applied the following fix up patch: From: Stephen Rothwell Date: Wed, 16 Jul 2014 18:20:59 +1000 Subject: [PATCH] memcg-deprecate-memoryforce_empty-knob-fix2 Signed-off-by: Stephen Rothwell --- mm/memcontrol.c | 1 - 1 file changed, 1 deletion(-) diff --git a/mm/memcontrol.c b/mm/memcontrol.c index 8fa6602a32cd..e1c9699b157b 100644 --- a/mm/memcontrol.c +++ b/mm/memcontrol.c @@ -5266,7 +5266,6 @@ static struct cftype mem_cgroup_files[] = { }, { .name = "force_empty", - .flags = CFTYPE_INSANE, .write = mem_cgroup_force_empty_write, }, { -- 2.0.1 -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
