Subject[PATCH 0/6 v5] pagemap handles transparent hugepage
Date
Hi,

In this version, I applied the feedbacks about the return value of
__pmd_trans_huge_lock() and renaming newly added components.
I hope these patches go into mainline.

Naoya Horiguchi (6):
pagemap: avoid splitting thp when reading /proc/pid/pagemap
thp: optimize away unnecessary page table locking
pagemap: export KPF_THP
pagemap: document KPF_THP and make page-types aware of it
introduce pmd_to_pte_t()
pagemap: introduce data structure for pagemap entry
