Subject: [PATCH 4.19 133/142] flexfiles: enforce per-mirror stateid only for v4 DSes
4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tigran Mkrtchyan <tigran.mkrtchyan@...y.de>
commit 320f35b7bf8cccf1997ca3126843535e1b95e9c4 upstream.
Since commit bb21ce0ad227 we always enforce per-mirror stateid.
However, this makes sense only for v4+ servers.
