From b24eaf52ade5e5f1e94243f727d4c0f6d0fccdf5 Mon Sep 17 00:00:00 2001

From: Richard Retanubun RichardRetanubun@RuggedCom.com Date: Fri, 12 Dec 2008 10:23:45 -0500 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.

Signed-off-by: Richard Retanubun RichardRetanubun@RuggedCom.com --- 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.
