As seen in `man mke2fs`:

       -m reserved-blocks-percentage
              Specify  the  percentage  of  the filesystem blocks
              reserved for the super-user.  This  value  defaults
              to 5%.

This would also apply to ext3, as that just ext2 + journal, but I
don't know whether other filesystems (reiser, xfs, jfs...) also
create a reserve by default.

The purpose of this is basically to ensure that user processes are
not able to bring the system down by filling up the disk, preventing
root-owned daemons from being able to function.
