That's right, systems will never shut down. 8)
Seriously though, I'm in the process of replacing a number of the
ad-hoc event handler callout lists in the kernel (most notably the
at_shutdown and apm* lists) with a generic implementation.
The upshot of this is that at_shutdown will go away. The old calls:
at_shutdown(func, arg, queue)
at_shutdown_pri(func, arg, queue, priority)
will be replaced with
EVENTHANDLER_REGISTER(queue, func, arg, priority)
Due to the way the event handler works, this means that event handler
functions which were originally
void func(int howto, void *arg)
will become
void func(void *arg, int howto)
This is unfortunate but more or less unavoidable.
I will be converting all users of at_shutdown in the kernel to the new
mechanism, but it's of some concern to me that there may be external
code using the old at_shutdown* interfaces that may benefit from a
compatibility interface (which could be done relatively easily).
Is there significant interest in having this implemented?
