Side note: it would have been really nice to see links to the actual
problem reports in the revert commit.

Yes, there's a "Link:" line there, but that points to the
less-than-useful patch submission for the revert, not to the actual
_reasons_ for the revert.

Now I'm looking at that revert, and I have absolutely no idea why it
happened. Only a very vague "there are still reported regressions
happening".

I've pulled it, but wanted to just point out that when there's some
fairly fundamental revert like this, it really would be good to link
to the problems, so that when people try to re-enable it, they have
the history for why it didn't work the first time.

Now all that history is basically lost (well, hopefully Saravana and
you actually remember, but you get my point).
