Ok, I did some half-arsed testing. I didn't have a kernel with
USERFAULT enabled, but I did compile one with both patches in place
and I don't see a hang with the test program. Of course, since I
didn't test with an unpatched kernel that would show the hang in the
first place, it's entirely possible that my "no hang" result is due to
something else. And I didn't bother to test the two patches
independently either.
But at least on the face of it, those patches fix the problem. Dmitry?
