| |
The scheduled cgroup writeback support requires blkio to be initialized before memcg as memcg needs to provide certain blkcg related functionalities. Relocate blkio so that it's right above memory.
Signed-off-by: Tejun Heo <tj@kernel.org> --- Hello,
These are two trivial patches to prepare for the cgroup writeback support. Applying to cgroup/for-3.20.
Thanks.
