Thanks for your feedback.

Over the years, I've been forwarded numerous emails from VMD customers
praising it's ability to prevent Linux kernel panics upon hot-removals
and inserts of U.2 NVMe drives. Many were migrating from SATA drives,
which didn't have this issue, and considered it a showstopper to NVMe
adoption. I hope we can all agree reliable and robust hot-plug support
adds value.
