Subject[PATCH 0/9] Convert all THP vmstat counters to pages
Date
Hi,

This patch series is aimed to convert all THP vmstat counters to pages
and the kernel stack vmstat counter to bytes.

The unit of some vmstat counters are pages, the unit of some vmstat counters
are bytes, the unit of some vmstat counters are HPAGE_PMD_NR, and the unit
of some vmstat counters are KiB. When we want to expose these vmstat counters
to the userspace, we have to know the unit of the vmstat counters is which
one. It makes the code complex.

This patch series can make the code simple. And the unit of the vmstat
counters are either pages or bytes.

This was inspired by Johannes and Roman. Thanks to them.
