Subject: [PATCH v2 0/2] mm/userfaultfd: fix and cleanup for migration entries with uffd-wp
Date: Wed, 5 Apr 2023 18:02:34 +0200 [thread overview]
Message-ID: <20230405160236.587705-1-david@redhat.com> (raw)
One fix and one cleanup.
uffd-wp migration entry handling for PTE/PMDs should now be fairly similar
code-wise.
v1 -> v2:
- Add RB's
- "mm/userfaultfd: fix uffd-wp handling for THP migration entries"
-> pmd_swp_uffd_wp(*pvmw->pmd) -> pmd_uffd_wp(pmdval)
