danvet · danvet · commit 437c30874cb9 · 2016-08-05T22:30:56.000+02:00
~jiffie and a few usecs is 3 orders of magnitude different. A bit much. This was changed in commit ca5b721 Author: Chris Wilson <chris@chris-wilson.co.uk> 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).
