First part is fixing discard in combination with -blockdev. The option needs to be set for the whole throttle->fmt->file chain to make it work.
Second part is fixing bug #6543, qcow2 can grow beyond what qemu-img measure reports, because of fragmentation when the discard-no-unref option is not used. There is a fix-6543 branch on my staff repo, should the patches touching tests be messed up again because of the overly long line in the expected test output.
