Subject: fix for crashes provoked by UMS mode
Date: Mon,  7 Jan 2013 18:21:56 -0500	[thread overview]
Message-ID: <1357600919-9967-1-git-send-email-ihadzic@research.bell-labs.com> (raw)

At Dave's request I ran some regression tests on my CS-refactoring
patches [1] against old UMS userspace. The tests have revealed
that the current kernel can be provoked into crashing in UMS mode
(and the problem is unrelated to refactoring of CS code; it has
been here before).

The following patches will fix the problem that I discovered
while testing (and they should probably go to drm-fixes branch).
First two patches are the fix for the acute problem, while
the third patch is a fix for an incidental finding uncovered
while debugging the problem.
