5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>
[ Upstream commit b876d708316bf9b6b9678eb2beb289b93cfe6369 ]
The change attribute is always set by all NFS client versions so get rid
of the open-coded version.
Fixes: 3cc55f4434b4 ("nfs: use change attribute for NFS re-exports")
