SubjectRe: [PATCH] nvmet: fix nvmet_execute_write_zeroes function

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?
