Subject: [PATCH v2 1/3] crash: add VMCOREINFO macro for anonymous structs
Date: Fri, 1 May 2020 11:46:08 +0206 [thread overview]
Message-ID: <20200501094010.17694-2-john.ogness@linutronix.de> (raw)
In-Reply-To: <20200501094010.17694-1-john.ogness@linutronix.de>
Some structs are not named and are only available via their typedef.
Add a VMCOREINFO macro to export field offsets for such structs.
