From: Trond Myklebust Date: Mon, 14 Nov 2016 19:34:18 +0000 (-0500) Subject: pNFS: Clear NFS_LAYOUT_RETURN_REQUESTED when invalidating the layout stateid X-Git-Tag: v4.8.17~15 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=abb2903f1ac21ba17698728d17c442deb3266ab8;p=thirdparty%2Fkernel%2Fstable.git 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...")
