"This is starting to get beyond frustrating for me," complained David Miller of the latest merge window, launching what turned into a very lengthy and ongoing discussion about the Linux kernel development process. The concept of a regular "merge window" was first discussed in July of 2005 with the release of the 2.6.24-rc4 kernel, following the 2005 Developers' Summit. From 2.6.14 on, the release of each official 2.6.y kernel has been followed by a two week period during which major changes are merged into the kernel, followed by a 2.6.y-rc1 release. David complained that this particular merge window has been more painful than others, "the tree breaks every day, and it's becoming an extremely non-fun environment to work in. We need to slow down the merging, we need to review things more, we need people to test their [...] changes!"

During the lengthy discussion, Linux creator Linus Torvalds explained:

"The notion that we should even _try_ to aim to slow things down, that one I find unlikely to be true, and I don't even understand why anybody would find it a logical goal? Of course, you will have fewer new bugs if you have fewer changes. But that's not a goal, that's a tautology and totally uninteresting. A small program is likely to have fewer bugs, but that doesn't make something small 'better' than something large that does more. Similarly, a stagnant development community will introduce new bugs more seldom. But does that make a stagnant one better than a vibrant one? Hell no. So what I'm arguing against here is not that we should aim for worse quality, but I'm arguing against the false dichotomy of believing that quality is incompatible with lots of change."
