| Subject: nvme/multipath: Disable runtime writable enabling parameter |
| |
| From: Keith Busch <keith.busch@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. |
