Subject: [PATCH] The ending LBA is inclusive. Hence, the partition size should
be
((ending-LBA + 1) - starting-LBA) to get the proper partition size.
This is confirmed against the results from the parted tool.
(e.g. use parted /dev/sda -s unit S print) and observe the size.

Hi Wolfgang,
Apologies for the 'custodianship' assumption audacity :)
Let me know if there is a more proper 'channel' for this
and I'll stop bugging you.
