From 8f674e0e12e4b88fc035948612a0b0949e0ad892 Mon Sep 17 00:00:00 2001 From: Janosch Frank Date: Thu, 11 Aug 2022 12:10:54 +0000 Subject: [PATCH 22/42] dump: Replace opaque DumpState pointer with a typed one MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit RH-Author: Cédric Le Goater RH-MergeRequest: 226: s390: Enhanced Interpretation for PCI Functions and Secure Execution guest dump RH-Bugzilla: 1664378 2043909 RH-Acked-by: Thomas Huth RH-Acked-by: Cornelia Huck RH-Acked-by: Jon Maloy RH-Commit: [22/41] 5f071d7ef441ae6f5da70eb56018c4657deee3d7 It's always better to convey the type of a pointer if at all possible. So let's add the DumpState typedef to typedefs.h and move the dump note functions from the opaque pointers to DumpState pointers.
