There is an patch at http://kanga.kvack.org/~blah/aio/ to implement
aio facilities that allow userspace to support the Posix AIO API.
It works by introducing a new, NetWare-inspired abstraction: worktodos.
Worktodos combine taskqueues (Linux´s way to get a process context for
a random kernel item) with waitqueue and thus allow very intresting
asynchronous kernel jobs.
Whip me. Beat me. Make me maintain AIX.
