I 100% agree.

Unfortunately, we don't have a good system for a "bug #". Most kernel
developers hate bugzilla, and I think that includes Linus ;-) Which
means, unless Linus builds us a new bug tracking system, there wont be
any mandate for it.

I would love all bug fixes to come with a test (when possible).

Well, we have a selftest directory that should include all of these.
And most people run them on either a test box or a VM.

Your "b" above is what I would like to push. But who's going to enforce
this? With 10,000 changes per release, and a lot of them are fixes, the
best we can do is the honor system. Start shaming people that don't
have a regression test along with a Fixes tag (but we don't want people
to fix bugs without adding that tag either). There is a fine line one
must walk between getting people to change their approaches to bugs and
regression tests, and pissing them off where they start doing the
opposite of what would be best for the community.
