You seem to be making an argument for more automation here, not an argument for less code. Or is there some upper bound to the size of the kernel, that might be lifted by adding maintainers?

So the effective cost of > keeping code around in the tree is going up. But if maintenance cost rises due to good analysis, the value of the code should rise too. So what's the problem? It seems to me that the real problem is too many analyses that generate pedantic noise and no tangible improvement in code quality or value. > I get a substantial amount of code analysis mail about drivers nobody > have touched in a decade or more. > When stable, mature code fails analysis, the analysis is also questionable (in the absence of real examples). > Consequently, I am much more inclined to remove drivers than I have been > in the past.

Many issues detected by automatic analyzers can be fixed with automatic code transformation tools. This kind of solution works tree-wide, so even if some defect in your driver is "yours and yours alone", the solution will probably come from others. This email, like yours, is just hand-waving. So feel free to ignore it or (preferably) provide evidence of real defects.
