There are code such like this in several places in aufs.
#ifdef HINOTIFY
test_hinotify()
{
// some code
}
#else
test_hinotify()
{
// empty
}
#endif
if (test_hinotify()) {
// do something
}
Disabling HINOTIFY makes test_hinotify() empty and our compiler will
totally remove the 'do something' block. It contributes both of code
size and the speed, since 'some code' will not be executed either.
