description="
Kernel Asynchronous I/O (AIO) support for GNU/Linux.

AIO enables even a single application thread to overlap I/O operations
with other processing, by providing an interface for submitting one or
more I/O requests in one system call (io_submit()) without waiting for
completion, and a separate interface (io_getevents()) to reap
completed I/O operations associated with a given completion group.
