Subject: [PATCH v5 1/4] crash: add VMCOREINFO macro to define offset in a struct declared by typedef
Date: Thu, 9 Jul 2020 15:29:41 +0206 [thread overview]
Message-ID: <20200709132344.760-2-john.ogness@linutronix.de> (raw)
In-Reply-To: <20200709132344.760-1-john.ogness@linutronix.de>
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.
