There is not reason to artifically limit max_sectors in tcm_loop, set it to UINT_MAX to allow stressing the large I/O handling in the target core using the loopback driver. Also remove various superflous defines hiding the values set in the host template. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
