SubjectRe: [PATCH 5/8] block: improve automatic native capacity unlocking
From
From: Tejun Heo <tj@kernel.org>
Date: Sat, 15 May 2010 20:09:31 +0200

> Currently, native capacity unlocking is initiated only when a
> recognized partition extends beyond the end of the disk. However,
> there are several other unhandled cases where truncated capacity can
> lead to misdetection of partitions.
>
> * Partition table is fully beyond EOD.
>
> * Partition table is partially beyond EOD (daisy chained ones).
>
> * Recognized partition starts beyond EOD.
>
> This patch updates generic partition check code such that all the
> above three cases are handled too. For the first two, @state tracks
> whether low level partition check code tried to read beyond EOD during
> partition scan and triggers native capacity unlocking accordingly.
> The third is now handled similarly to the original unlocking case.
