As far as I know SPC-4 does not allow unaligned unmap requests to fail. The only phrase I found in SPC-4 about unaligned unmap requests is the following: "An unmap request with a starting LBA that is not optimal may result in unmap operations on fewer LBAs than requested." Hence check that unaligned unmap requests succeed. Signed-off-by: Bart Van Assche <bvanassche@acm.org>
