[v2,0/4] mm/hugetlb: fix /sys and /proc fs dealing with persistent hugepages

Message

Xueshi Hu Aug. 6, 2023, 7:48 a.m. UTC

The meaning persistent huge pages is ambiguous both in documentation and
code implementation. About the bugfix, see the details in the commit 
message in patch 1 and 3. 

Additionally, code relevant with hstate:max_huge_pages can be simplified
easily after the bugfix, do it in patch 2.

v1 -> v2
1. Revise the commit message in patch 1.
3. Add fix tag in patch 3.
4. Add the patch 4 to correct documentation.
