Thx for the report. Linus just reverted the commit 07ed11afb68 you
mentioned in your initial mail (I put that quote in again, see above):

3628e0383dd349 ("Reapply "drm/qxl: simplify qxl_fence_wait"")
https://git.kernel.org/torvalds/c/3628e0383dd349f02f882e612ab6184e4bb3dc10

So this hopefully should be history now.

Ciao, Thorsten
