Proper design of userland kernel APIs is changing with the
times. Once ioctl() was the catch-all way to communicate
things, but that was back when both software and hardware
stayed the same from boot to crash. With loadable modules
and pluggable hardware, ioctl() is just not enough.
Poul-Henning will talk about the concerns to be addressed
and methods available to design modern APIs, and go through
a number of his creatations: GEOMs XML export and g_ctl().
nmount(2). device_statistics export etc.
