As does memclear_highpage_flush(). Some of my code looks like:
void some_func(...)
{
if (foo)
return do_foo(...);
if (bar)
return do_bar(...);
...
}
do_foo() and do_bar() also return void. Saves an extra line for the
return statment and the brackets.

Doesn't help in the code you quoted, of course.
