new howto: User Space - Kernel Space communication"

Hi

I'd like to write a HOWTO for "User Space - Kernel
Space communication".
Currently it is hard for a developer to get an overview
about the 
available mechanism for user space - kernel space
communication. 
Therefore the goal of this HOWTO is to give an introduction
to each of 
these communication mechanisms.

I will cover the following topics:
- procfs
- sysfs
- configfs
- debugfs
- sysctl
- character device
- udp sockets
- netlink sockets (with focus to generic netlink sockets)
- ioctl (with character device)
- writing new system calls
- signals
- mmap (with debug fs)

Each of these topics will cover the following sections:
- short description and design principles
- intended use
- pointers to further information
- code example

Is there an interest in such a HOWTO?

Thanks for your comments!

Ariane

as part of a course i gave in basic kernel programming, i
covered a
number of those topics, so i'd be interested in
collaborating on that.
the one thing i'd be careful about is emphasizing those
features that
are encouraged, and de-emphasizing the ones that are
deprecated, such
as ioctl() calls.

more later.
