mtd->size revisited

[Bruce_Leonard at selinc.com]

Thanks Vernon, Trent, and Artem for the suggestions, there are some really 
good ones that look like they'll save me some pain that I wouldn't have 
thought of.  Artem, I'll definety try and get in touch with dwmw2, thanks 
for the POC.  I'm not entirely clear on your suggestion Artem, but (if you 
agree) I think we should probably take further discussions of it out of 
the mailing list rather than creating a lot of noise for the people on the 
list who do understand ;).

Thanks again to all.

Bruce
