You're my hero :-).

Do you only accept github pull requests or do you accept patches via
linux-block as well?

As a side note, I'm currently working on a partition table fuzzer to
stress block/partitions/*.c a bit. I think this could be included into
your framework as well (it's only one .c file currently with no external
dependencies).
