Subject: [PATCH 0/5] Cleanup and fixup for mm/migrate.c
Date: Sat, 20 Mar 2021 05:36:56 -0400 [thread overview]
Message-ID: <20210320093701.12829-1-linmiaohe@huawei.com> (raw)
Hi all,
This series contains cleanups to remove unnecessary VM_BUG_ON_PAGE and
rc != MIGRATEPAGE_SUCCESS check. Also use helper function to remove some
duplicated codes. What's more, this fixes potential deadlock in NUMA
balancing shared exec THP case and so on. More details can be found in
the respective changelogs. Thanks!

mm/migrate.c: remove unnecessary VM_BUG_ON_PAGE on
putback_movable_page()
mm/migrate.c: remove unnecessary rc != MIGRATEPAGE_SUCCESS check in
'else' case
mm/migrate.c: fix potential indeterminate pte entry in
migrate_vma_insert_page()
mm/migrate.c: use helper migrate_vma_collect_skip() in
migrate_vma_collect_hole()
mm/migrate.c: fix potential deadlock in NUMA balancing shared exec THP
