Subject: [PATCH 0/2] mm/uffd: Fix vma check
Date: Mon, 24 Oct 2022 15:33:34 -0400 [thread overview]
Message-ID: <20221024193336.1233616-1-peterx@redhat.com> (raw)
I just got time to have a closer look on the uffd-wp triggering of the
warning here:
https://lore.kernel.org/all/YzeR+R6b4bwBlBHh@x1n/T/#u
It turns out to be a wrong check on vma, and with the fix attached we
should be able to remove the ugly macro checks. Sorry for the bothersome.
Please have a look, thanks.
