Yes, my commits are mostly unreviewed. It's the norm now. Willing reviewers
don't exist anymore. I don't really mind that my patches are not reviewed,
but whoever complains that I push unreviewed commits should ask himself why
he didn't review them in their review period. That applies to everybody.
Either review regularly or accept that unreviewed commits are normal.

Secondly, past commits can't break future commits, so don't say it breaks
stuff again. It's illogical.

There may be multiple reasons why the commit exists. As long as reverting
it doesn't break piglit / radeonsi, I'm OK with the reverting.
