In article <200310161255.36380.ioe-lkml@rameria.de>,
Ingo Oeser  <ioe-lkml@rameria.de> asked:

| Sorry, but I still don't get, what a "const volatile" is supposed to mean.

It's a volatile which we're not allowed to change.

The ones which I always have to look at multiple times are the "const
pointer to volatile" and "volatile pointer to const." As in unchanging
pointer to a volatile datum, or a volatile pointer to unchanging data.
