That's an ACK for the null vs whitespace changes.  The NAK
for this patch still stands.

Who are these people and why aren't they on the nvme list?  The
dm-mpath approach is fundamentally wrong for NVMe, and especially
NVMeOF - e.g. for NVMeOF we have the mandatory keep alive, so doing
any wonky path checking from userspace is just going to create
problems.
