Subject: [PATCH 00/11] mm: page_vma_mapped_walk() cleanup and THP fixes
Date: Wed, 9 Jun 2021 23:31:57 -0700 (PDT) [thread overview]
Message-ID: <589b358c-febc-c88e-d4c2-7834b37fa7bf@google.com> (raw)
Here is the promised splitup of what I posted a few days ago as
5/7 mm/thp: fix page_vma_mapped_walk() if huge page mapped by ptes.
These are against 5.13-rc5 plus yesterday's mm/thp series:
https://lore.kernel.org/linux-mm/f7fc2e72-b8b1-f132-cdb2-1b256a6f2de@google.com/T/#u
(sorry about the misthreading, I missed linux-mm and lkml at first).
03/10 and 04/10 of that series also touched mm/page_vma_mapped.c.
I've marked all of these for stable: many are merely cleanups,
but I think they are much better before the main fix than after.
01/11 makes the opposite cleanup to the earlier 5/7: that preferred
to use pvmw->page, this prefers to use page - it could go either way.
11/11 is a new fix that I noticed while splitting up.
01/11 mm: page_vma_mapped_walk(): use page for pvmw->page
02/11 mm: page_vma_mapped_walk(): settle PageHuge on entry
03/11 mm: page_vma_mapped_walk(): use pmd_read_atomic()
04/11 mm: page_vma_mapped_walk(): use pmde for *pvmw->pmd
05/11 mm: page_vma_mapped_walk(): prettify PVMW_MIGRATION block
06/11 mm: page_vma_mapped_walk(): crossing page table boundary
07/11 mm: page_vma_mapped_walk(): add a level of indentation
08/11 mm: page_vma_mapped_walk(): use goto instead of while (1)
09/11 mm: page_vma_mapped_walk(): get vma_address_end() earlier
10/11 mm/thp: fix page_vma_mapped_walk() if THP mapped by ptes
11/11 mm/thp: another PVMW_SYNC fix in page_vma_mapped_walk()
