From 2b860db67ff3ce886fcb35289a9283a041cce6a4 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 18 Jul 2012 20:03:05 +0200 Subject: [PATCH] drm/i915: Reserve ioctl numbers for set/get_caching I'm planing to merge this next week for 3.7, but I'd like to avoid stupid conflicts with the exsting userspace when merging the new reg_read ioctl (which doesn't have userspace yet, but this caching interface has). Header extracted from Chris Wilson's patch, but fix up the copy&pasted comment in the interface struct.
