svn commit: r317283 - head/sbin/fsck_ffs

[Pedro F. Giffuni]

Author: pfg
Date: Sat Apr 22 14:50:11 2017
New Revision: 317283
URL: https://svnweb.freebsd.org/changeset/base/317283

Log:
  fsck_ffs: Unsign some variables and make use of reallocarray(3).
  
  Instead of casting listmax and numdirs to unsigned values just define
  them as unsigned and avoid the casts. Use reallocarray(3).
  
  While here, fs_ncg is already unsigned so the cast is unnecessary.
