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?
