New Revision: 251798
URL: http://svnweb.freebsd.org/changeset/base/251798

Log:
  MFC	r251677:
  
  Relax some unnecessary unsigned type changes in ext2fs.
  
  While the changes in r245820 are in line with the ext2 spec,
  the code derived from UFS can use negative values so it is
  better to relax some types to keep them as they were, and
  somewhat more similar to UFS. While here clean some casts.
