Hello, guys. This patch replaces cgroup file interface with cftype based one which allows dynamic additions and removals of cftype arrays whether the target subsystem is attached or not. This can be used to make subsys rebinding via remount work properly but I intentionally avoided doing that at the moment. This makes cgroup population simpler for controllers and will be used to allow controllers to be more dynamic. e.g. blkio subsys has sub-policies which may come and go while blkio subsys is attached and it currently uses fixed set of files which stays blank if not in use. This will also be useful for implementing unified hierarchy.

If ->create() doesn't work for whatever reason, can you please explain it to me so that we can find a proper solution? diffstat follows. block/blk-cgroup.c | 10 - include/linux/cgroup.h | 56 +++++-- kernel/cgroup.c | 351 ++++++++++++++++++++++++++++++++++------------ kernel/cgroup_freezer.c | 11 - kernel/cpuset.c | 31 +--- kernel/sched/core.c | 16 -- mm/memcontrol.c | 31 ---- net/core/netprio_cgroup.c | 9 - net/ipv4/tcp_memcontrol.c | 8 - net/sched/cls_cgroup.c | 9 - security/device_cgroup.c | 10 - 11 files changed, 341 insertions(+), 201 deletions(-) Thanks. -- tejun [1] http://thread.gmane.org/gmane.linux.kernel.cgroups/1192/focus=22611 _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/containers
