4.16-stable review patch. If anyone has any objections, please let me know.
------------------
From: Keith Busch <keith.bu...@intel.com>
[ Upstream commit 5cadde8019a6a80550fdde92d5a3327565974eab ]
We can't allow the user to change multipath settings at runtime, as this
will create naming conflicts due to the different naming schemes used
for each mode.
