From 7c5222c8d8f52869af95e8ff3b5171138ae2d0ae Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Fri, 5 Aug 2016 18:11:24 +0200 Subject: [PATCH] drm/i915: Update comment before i915_spin_request ~jiffie and a few usecs is 3 orders of magnitude different. A bit much. This was changed in commit 1dd696678d323398ad2a18cc07e6d9091ed3887e Author: Chris Wilson Date: Fri Dec 11 11:32:58 2015 +0000 drm/i915: Limit the busy wait on requests to 5us not 10ms! But probably missed the comment since the change was non-local to the comment. v2: Polish comment more (Chris).
