Allow people to increase the number of inode available to them by using the disk space they should already have.
for the sake of example, currently I have access to a 160GB disk space server and i am only using 22 GB of it. i can't add more files because i seem to be out of inode space. Inodes are made from disk space being used as a table to map out other files. Why can't this table be increased using the space i already have access to so i can take advantage of all my disk space.
