Subject: [PATCH v1 0/2] mm/userfaultfd: fix and cleanup for migration entries with uffd-wp
Date: Wed,  5 Apr 2023 16:25:33 +0200	[thread overview]
Message-ID: <20230405142535.493854-1-david@redhat.com> (raw)

One fix (I have a simple reproducer but it's too long to paste it into
the commit) and one cleanup.

uffd-wp migration entry handling for PTE/PMDs should now be fairly similar
code-wise.
