Subject: [PATCH v2 00/10] s390: PG_arch_1+folio cleanups for uv+hugetlb
Date: Fri, 12 Apr 2024 16:21:10 +0200 [thread overview]
Message-ID: <20240412142120.220087-1-david@redhat.com> (raw)
This is v2 of [1] with changed subject:
"[PATCH v1 0/5] s390: page_mapcount(), page_has_private() and PG_arch_1"
Rebased on s390x/features which contains the page_mapcount() and
page_has_private() cleanups, and some PG_arch_1 cleanups from Willy. To
compensate, I added some more cleanups ;)
One "easy" fix upfront. Another issue I spotted is documented in [1].
Once this hits upstream, we can remove HAVE_ARCH_MAKE_PAGE_ACCESSIBLE
from core-mm and s390x, so only the folio variant will remain.
Compile tested, but not runtime tested with UV, I'll appreciate some
testing help from people with UV access and experience.
[1] https://lkml.kernel.org/r/20240404163642.1125529-1-david@redhat.com
v1 -> v2:
* Rebased on s390x/features:
* "s390/hugetlb: convert PG_arch_1 code to work on folio->flags"
-> pmd_folio() not available on s390x/features
* "s390/uv: don't call folio_wait_writeback() without a folio reference"
-> Willy's folio conversion is in s390x/features
* "s390/uv: convert PG_arch_1 users to only work on small folios"
-> Add comments
* Rearrange code and handle split_folio() return values properly. New
patches to handle splitting:
-> "s390/uv: gmap_make_secure() cleanups for further changes"
-> "s390/uv: split large folios in gmap_make_secure()"
* Added more cleanups:
-> "s390/uv: make uv_convert_from_secure() a static function"
-> "s390/uv: convert uv_destroy_owned_page() to uv_destroy_(folio|pte)()"
-> "s390/uv: convert uv_convert_owned_from_secure() to
uv_convert_from_secure_(folio|pte)()"
-> "s390/mm: implement HAVE_ARCH_MAKE_FOLIO_ACCESSIBLE"
