Subject: [PATCH 0/2] Support hugetlb charge moving at task migration

Hi,

Now in the hugetlb cgroup, charges associated with a task aren't moved
to the new hugetlb cgroup at task migration, which is odd for hugetlb
cgroup usage. This patch set adds hugetlb cgroup charge moving when
migrate tasks among cgroups, which are based on the memcg charge moving.

Please help to review. Thanks.

Baolin Wang (2):
  hugetlb_cgroup: Add interfaces to move hugetlb charge at task
    migration
  hugetlb_cgroup: Add post_attach interface for tasks migration
