Date: Mon, 4 Jul 2022 21:21:46 +0800
Patch series "A few cleanup patches for huge_memory", v3.
This series contains a few cleaup patches to remove duplicated codes,
add/use helper functions, fix some obsolete comments and so on. More
details can be found in the respective changelogs.
This patch (of 16):
Arches with special requirements for evicting THP backing TLB entries can
implement flush_pmd_tlb_range. Otherwise also, it can help optimize TLB
flush in THP regime. Using flush_pmd_tlb_range to take advantage of this
in move_huge_pmd.
