From e523ce8c99f9bbd530fda7d46c35409fee88a50f Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Mon, 14 Nov 2016 14:34:18 -0500 Subject: [PATCH] pNFS: Clear NFS_LAYOUT_RETURN_REQUESTED when invalidating the layout stateid commit ae5a459d5f65c3e83f3e14068dde5fb9c9d81807 upstream. We must ensure that we don't schedule a layoutreturn if the layout stateid has been marked as invalid. Fixes: 2a59a0411671e ("pNFS: Fix pnfs_set_layout_stateid() to clear...")
