This is nice from a code simplification point of view, and is mostly
orthogonal to the fast path walking.

I'd be inclined to call this combined function something like
path_lookup(), rather than path_init_walk() - the callers don't need to
know that it's an init followed by a walk, they just need to know that
it does a lookup.

Also, to avoid code duplication, is there any reason why path_lookup()
can't be implemented (possibly inlined) just as:

static int path_lookup(const char *name, struct nameidata *nd, int flags)
{

    if(!path_init(name, flags, nd))
	return 0;

    return path_walk(name, nd);

}
