But maybe I'm underestimating Linus.
What does it do? Just adds a pfn arg to flush_cache_page()? We do that sort of thing quite a lot, and I can help. A typical approach would be to send me a patch for the core kernel, a patch for x86 and a patch for arm. Any additional best-effort per-architecture patches would be appreciated as well, of course. I test of four architectures and compile on seven. arch maintainers will develop, test and submit their bits and when all the ducks are lined up I'll send it all off to Linus. The main problem is that people are hacking on mm/* all the damn time, so I have to live with massive reject storms during the changeover period. But that's my problem, not yours ;)
