I'd appreciate some feedback and testing, especially since I know of no programs which use AIO. This also fixes the non-platform independant way SYSCALL_MODULE_HELPER was implemented. It also adds a primative way to dynamically load a kevent subsystem as well as unloading it. It removes the aio_proc_rundown explicit call and uses the at_exit(9) functionality. Aio can even be unloaded if you're brave by setting a sysctl like I did for acceptfilters. Please, please, please give this some testing. I'd really like to get it committed, but I really need testers and concensus if I've done it the right way or not. I also hope this makes it more convient for you guys in the future (for adding features/debugging aio) http://people.freebsd.org/~alfred/aio_kld.diff Mr Cox or Mr Egge feel free to commit it if it works for you, or let me know if I can. thanks, -- -Alfred Perlstein [alfred@freebsd.org] 'Instead of asking why a piece of software is using "1970s technology," start asking why software is ignoring 30 years of accumulated wisdom.'
