(See Documentation/controllers/memory.txt) + Provides a memory resource controller that manages both page cache and + RSS memory. Note that setting this option increases fixed memory overhead - associated with each page of memory in the system. By this, - 20(40)bytes/PAGE_SIZE on 32(64)bit system will be occupied by memory - usage tracking struct at boot. Total amount of this is printed out - at boot. + associated with each page of memory in the system by 4/8 bytes + and also increases cache misses because struct page on many 64bit + systems will not fit into a single cache line anymore. Only enable when you're ok with these trade offs and really - sure you need the memory resource controller. Even when you enable - this, you can set "cgroup_disable=memory" at your boot option to - disable memory resource controller and you can avoid overheads. - (and lose benefits of memory resource contoller) + sure you need the memory resource controller. This config option also selects MM_OWNER config option, which could in turn add some fork/exit overhead. diff --git a/trunk/init/do_mounts_md.c b/trunk/init/do_mounts_md.c index 4d42f450b590..4c87ee1fe5d3 100644 --- a/trunk/init/do_mounts_md.c +++ b/trunk/init/do_mounts_md.c @@ -1,4 +1,4 @@ -#include + #include #include diff --git a/trunk/kernel/cgroup_freezer.c b/trunk/kernel/cgroup_freezer.c index 7fa476f01d05..e95056954498 100644 --- a/trunk/kernel/cgroup_freezer.c +++ b/trunk/kernel/cgroup_freezer.c @@ -162,13 +162,9 @@ static int freezer_can_attach(struct cgroup_subsys *ss, struct task_struct *task) { struct freezer *freezer;
