When trying to issue write_zeroes command against TARGET the nr_sector is being incremented by 1, which ends up hitting the following condition at __blkdev_issue_zeroout:
if ((sector | nr_sects) & bs_mask) return -EINVAL;
Causing the command to always fail. Removing the increment makes the command to work properly.
