[ Originally posted on 2002/09/11;  I just looked in 2.4.20-pre9 and it
was not there, hence the repost. ]

The DEF_HASH_FUZZY macro allows the user to template their hash; it
takes on a paramter for the hashing-function, namely HASHFN.  When used
with a hashing-function named anything other than 'hashfn()', a module
using the kernel's fuzzy hash implementation will not compile.

None of the in-kernel 2.4.x drivers use this primitive (yet) so it's no
wonder no one has spotted it.  The patch is very trivial and makes me
think that I am the very first user of the include/linux/ghash.h
hash-table primitive.   ;)

Bart.
