Subject: [PATCH v3 1/3] crash: add VMCOREINFO macro to define offset in a struct declared by typedef
Date:   Thu, 18 Jun 2020 16:55:17 +0206
Message-Id: <20200618144919.9806-2-john.ogness@linutronix.de>
In-Reply-To: <20200618144919.9806-1-john.ogness@linutronix.de>

Precedence: bulk

The existing macro VMCOREINFO_OFFSET() can't be used for structures
declared via typedef because "struct" is not part of type definition.

Create another macro for this purpose.
