Subject: [PATCH 0/5] create hugetlb flags to consolidate state
Date: Fri, 15 Jan 2021 16:31:00 -0800 [thread overview]
Message-ID: <20210116003105.182918-1-mike.kravetz@oracle.com> (raw)
While discussing a series of hugetlb fixes in [1], it became evident
that the hugetlb specific page state information is stored in a somewhat
haphazard manner. Code dealing with state information would be easier
to read, understand and maintain if this information was stored in a
consistent manner.
This series uses page.private of the hugetlb head page for storing a
set of hugetlb specific page flags. Routines are priovided for test,
set and clear of the flags.

RFC -> PATCH
Simplified to use a single set of flag manipulation routines (Oscar)
Moved flags and routines to hugetlb.h (Muchun)
Changed format of page flag names (Muchun)
Changed subpool routine names (Matthew)
More comments in code (Oscar)
Based on v5.11-rc3-mmotm-2021-01-12-01-57
Mike Kravetz (5):
hugetlb: use page.private for hugetlb specific page flags
hugetlb: convert page_huge_active() to HP_Migratable flag
hugetlb: only set HP_Migratable for migratable hstates
hugetlb: convert PageHugeTemporary() to HP_Temporary flag
hugetlb: convert PageHugeFreed to HP_Freed flag
