Hi,
I have written this patch so that /dev/raw now appears in a devfs
filesystem. I haven't tried to support the /dev/rawN devices because
I'm not sure that it would be worthwhile. (Seeing as you need to bind
them by hand manually anyway.)
Cheers,

Hi !
I have a program that need to have a precision better than 1ms.
Is there any way to change the "tick" field of the "adjtimex" function
