Subject: [PATCH v5 1/5] block: Add alternative_gpt_sector() operation
Date: Wed, 18 Aug 2021 03:55:43 +0300	[thread overview]
Message-ID: <20210818005547.14497-2-digetx@gmail.com> (raw)
In-Reply-To: <20210818005547.14497-1-digetx@gmail.com>

Add alternative_gpt_sector() block device operation which specifies
alternative location of a GPT entry. This allows us to support Android
devices which have GPT entry at a non-standard location and can't be
repartitioned easily.
