No, not necessarily.

It really comes down to this question:
What is the size on a directory supposed to signify?
It's certainly possible for us to fake up a size and stuff it into the
i_size field, but what should go there? Why 4096 and not 4097 or 4095?
What if the directory is bigger or smaller than a page?
Also, what sort of application is having problems with a directory of 0
size?
Asking this on fsdevel would probably be a good idea.
