I've been wondering about the same thing. A value that is appropriate for
the AFS implementation that's in the Linux kernel tree may be easier to
get through. (And no, on the whole I don't think client software should
care which AFS implementation happens to be loaded into the kernel at
the moment. For those who really want to know that, there is always
"rxdebug -version localhost afs3-callback".)
How about "AFS3", 0x33534641 ?
The correct header to add this in appears to be <linux/magic.h> (I'm
