Hi Jeff,
I noticed you've added a new flag to indicate that the drive has no seek costs and I figured it would be a good idea to use that on the MMC/SD cards.
Since the name isn't entirely clear in what is implied, I just wanted to check that there are no plans to assume that there is negligable request overhead for queues with this flag. I.e. the flag should indicate that the elevator doesn't have to care about seeks, but it should still try to merge requests to reduce the transaction overhead.
