Keith, I tested passing different values to the c (number of blocks) and 
s (64-bit LBA of first block to access) parameters, and it was failing. 
When I removed the +1, the command worked fine.

I used a simple script to validate this:

for s in {0..20}
     do
             for c in {0..20}
             do
                     nvme write-zeroes /dev/nvme0 -n 10 -s $s -c $c
             done
     done


Is there some other way to test it?
