Just wondering.  As a possible RFE.  Is there any reason the size of the
global bitmap could not be in the superblock?  It seems strange that in
order to find out how big the filesystem is I have to actually traverse
the filesystem.

Would it be a bad to but the size of the global bitmap into the
superblock?

Thanks,
