From 4230cea89cafb11b2c2e4dcac8b505e7a766b386 Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Tue, 14 Mar 2023 14:18:55 +0000 Subject: drm: Track clients by tgid and not tid MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Thread group id (aka pid from userspace point of view) is a more interesting thing to show as an owner of a DRM fd, so track and show that instead of the thread id. In the next patch we will make the owner updated post file descriptor handover, which will also be tgid based to avoid ping-pong when multiple threads access the fd.
