From 7d52cb88c9ca20c32288de6ed62b32410c936ccc Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 8 Mar 2017 15:12:43 +0100 Subject: drm: Remove drm_pending_event->pid We might as well dump the drm_file pointer, that's about as useful a cookie as the pid. Noticed while typing docs for drm_file and friends. Since the only consumer of this is the tracepoints I think we can safely change this - those tracepoints should not be uapi relevant at all. It all goes back to commit b9c2c9ae882f058084e13e339925dbf8d2d20271 Author: Jesse Barnes Date: Thu Jul 1 16:48:09 2010 -0700 drm: add per-event vblank event trace points which doesn't give a special justification for using pid over a pointer. Also note that the nouveau code setting it is entirely pointless: Since this isn't a vblank event, it will never hit the vblank tracepoints.
