Subject: [PATCH v1 0/2] mm: migrate: vm event counter for hugepage migration

Hi everyone,

I wrote patches introducing separate vm event counters for hugepage migration
(both for hugetlb and thp.)
Hugepage migration is different from normal page migration in event frequency
and/or how likely it succeeds, so maintaining statistics for them in mixed
counters might not be helpful both for develors and users.

Thanks,
Naoya Horiguchi
