[$] Bugs and fixes in the kernel history

Each new kernel release fixes a lot of bugs, but each release alsointroduces new bugs of its own. That leads to a fundamentalquestion: is the kernel community fixing bugs more quickly than it is addingthem? The answer is less than obvious but, if it could be found, itwould give an important indication of the long-term future of the kernelcode base. While digging into the kernel's revision history cannot give adefinitive answer to that question, it can provide some hints as to whatthat answer might be.
