[$] How many -stable patches introduce new bugs?

The -stable kernel release process faces a contradictory set of constraints.Developers naturally want to get as many fixes into -stable as possiblebut, at the same time, there is a strong desire to avoid introducing newregressions there. Each -stable release is, after all, intended to be morestable than its predecessor. At times there have been complaints that-stable is too accepting and too prone to regressions, but not manyspecifics. But, it turns out, this is an area where at least a little bitof objective research can be done.
