Apologies for the late post, I'm catching up on things, but this jumped out at 
me.

We went through a LOT of pain several years ago when people got into the mindset 
that a patch was acceptable if it fixed more people than it broke. eliminating 
that mindset did wonders for kernel stability.

Regressions are a lot more of a negative than bugfixes are a positive, a 10:1 
ratio of fixes to regressions is _not_ good enough.
