I want to stress that I'm not against your patches. I'm just trying to understand if there's a sensible way to use the write stream support in the kernel so that applcations don't /have/ to be converted. It sounds like that's hard, and without any specs or hardware, I'm not going to be able to even try to come up with solutions to that problem. I think it would make for interesting research, though. I recall a paper from one of the USENIX conferences that dealt with automatically identifying write streams on a network storage server, but alas, I can't find the reference right now. Anyway, thanks for taking the time to reply.
