2This patch fixes up the computation of nbinodes which would go
3negative due to an int overflow issue when nbblocks > 2Meg for
4a 2Gig or greater filesystem.
5
6The computation is now done as a float equation, since both nbblocks
7and bytes_per_inode are no floats, and then cast to int by assignment.
8
9int tmp_nbinodes = nbblocks * BLOCKSIZE / bytes_per_inode;
