[PATCH 8/9] mm/hugeltb_cgroup: convert hugetlb_cgroup_commit_charge*() to folios

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Convert hugetlb_cgroup_commit_charge*() to internally use folios to clean
up the code after __set_hugetlb_cgroup() was changed to take a folio.
