We have a lot of legacy device drivers kicking around in the tree so the default max request size remains the conservative SAFE_MAX_SECTORS (255). When a low level driver explicitly tells us that it can support bigger requests we take the opportunity to increase the soft limit to the block layer default (1024). Also, this function is generally called at block device creation time so it's not like we're overwriting an existing user setting. -- Martin K.
