Correct. There was agreement a very long time ago that code should not patch
the syscall table (for one its not safe). AFS probably needs fixing so the
AFS syscall hook is exported portably and nicely in the syscall code.

This wants fixing in 2.5 too - basically

static int (*afs_syscall)(...);
sys_afs_syscall(...)
{
	if(afs_syscall)
		return afs_syscall(....)
	return -ENOSYS;
}

EXPORT_SYMBOL(afs_syscall)
