From 21e31401fc4595aeefa224cd36ab8175ec867b87 Mon Sep 17 00:00:00 2001 From: Anna Schumaker Date: Thu, 3 Dec 2020 15:18:39 -0500 Subject: NFS: Disable READ_PLUS by default We've been seeing failures with xfstests generic/091 and generic/263 when using READ_PLUS. I've made some progress on these issues, and the tests fail later on but still don't pass. Let's disable READ_PLUS by default until we can work out what is going on.
