BROKEN is still in use, with dozen or so cases for last year. See for example: commit 9d60d93198c62ac3b3e59e8bba7079646c972a4c Author: J. Bruce Fields <bfields@redhat.com> Date: Mon Aug 26 10:28:58 2019 -0400 Deprecate nfsd fault injection That said, your suggestions are pretty good. v2 coming in a moment. -Emil

Drivers have not seen any love for years. Be that fixes or improvements, or cosmetics like introducing symbolic names, style and code-flow polish. Seemingly the maintainer has also disappeared years ago :-\ Considering nouveau supports all that hardware (modulo nv03) just mark these as obsolete/broken, referring to nouveau in the help text.
