[PATCH 0/5] Cleanup and fixup for khugepaged

[Miaohe Lin]

Hi all,
This series contains cleanups to remove unneeded return value, use
helper function and so on. And there is one fix to correct the wrong
result value for trace_mm_collapse_huge_page_isolate().

More details can be found in the respective changelogs. Thanks!

Miaohe Lin (5):
  khugepaged: remove unneeded return value of
    khugepaged_collapse_pte_mapped_thps()
  khugepaged: reuse the smp_wmb() inside __SetPageUptodate()
  khugepaged: use helper khugepaged_test_exit() in __khugepaged_enter()
  khugepaged: remove unnecessary mem_cgroup_uncharge() in
    collapse_[file|huge_page]
  khugepaged: fix wrong result value for
    trace_mm_collapse_huge_page_isolate()
