Subject: [PATCH 4/4] x86: select HAVE_MOVE_PMD for faster mremap (v1)
Date: Fri, 12 Oct 2018 18:32:00 -0700 [thread overview]
Message-ID: <20181013013200.206928-5-joel@joelfernandes.org> (raw)
Message-ID: <20181013013200.PzCgXsS2d9otR--Hb_mylFpoESB1adbCsHdC6baDpCo@z> (raw)
In-Reply-To: <20181013013200.206928-1-joel@joelfernandes.org>
Moving page-tables at the PMD-level on x86 is known to be safe. Enable
this option so that we can do fast mremap when possible.
