From 0d6f55403a47b317c0d9511a80545c19ab0ef52f Mon Sep 17 00:00:00 2001 From: John Ogness Date: Thu, 9 Jul 2020 15:29:41 +0206 Subject: crash: add VMCOREINFO macro to define offset in a struct declared by typedef 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.
