This doesn't do anything - it would remove a "found" version, but this
bug was never found there.

I was able to narrow this down a bit with snapshots of each release:

- broken in squeeze, wheezy, and jessie
- partly fixed in stretch and buster (wchan shows function names for
  most sleeping threads, subject to privilege check)
- broken again in bullseye
- fully fixed in 5.16.14-1 (wchan shows function names for all sleeping
  threads, subject to privilege check)

Given that, I think this can be closed with version 5.16.14-1.  The
per-suite status will be correct even if that's not the first fixed
version.
