From 731e46c032281601756f08cfa7d8505fe41166a9 Mon Sep 17 00:00:00 2001 From: Francois Dugast Date: Thu, 13 Jun 2024 19:03:48 +0200 Subject: [PATCH] drm/xe/exec_queue: Rename xe_exec_queue::compute to xe_exec_queue::lr The properties of this struct are used in long running context so make that clear by renaming it to lr, in alignment with the rest of the code.
