I've looked through the changeset. The only real changes with regards to
the existing code is the handling of the freeing of the identification
cookie. There used to be an "efi_gpt_free_identify_partition_cookie" hook
and now it is NULL. Besides that I think the block count calculation was
and still is wrong. It should be "end_block - start_block + 1". That would
also make it symetric with the new "SetBlockCount()" method.
Best regards,
