Subject: [PATCH v3 0/2] Performance regression due to XSA-336
Date: Mon, 29 Mar 2021 17:15:00 -0400 [thread overview]
Message-ID: <1617052502-14181-1-git-send-email-boris.ostrovsky@oracle.com> (raw)
The first patch addresses performance regression introduced by XSA-336 fixes.
This patch could be considered as a candidate for inclusion in 4.15.
The second patch is a minor cleanup and can safely wait until after 4.15.
Boris Ostrovsky (2):
x86/vpt: Do not take pt_migrate rwlock in some cases
x86/vpt: Simplify locking argument to write_{un}lock
