Yeah, but I have lots of competing thoughts about this. For the time being I'm focusing on simplifying the mechanisms that support the sys_io_*() interface so I never ever have to debug fs/aio.c (also known as chewing glass to those of us with the scars) again. That said, I'll gladly work closely with developers who are seriously considering putting some next gen interface to the test. That todo item about producing documentation and distro kernels is specifically to bait Uli into trying to implement posix aio on top of syslets in glibc. 'cause we can go back and forth about potential interfaces for, well, how long as it been? years? I want non-trivial users who we can measure so we can *stop* designing and implementing the moment something is good enough for them. - z - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
