The block device set_capacity() interface is already defined and was
implemented for the IDE disk driver some time ago. The purpose of
Tejun's work on sd and libata is to implement this existing interface
and so avoid a regression when users switch from IDE to libata-based
drivers. I don't see why he should have to replace the interface as
well.
