New Revision: 368773
URL: https://svnweb.freebsd.org/changeset/base/368773

Log:
  Rename pass4check() to freeblock() and move from pass4.c to inode.c.
  The new name more accurately describes what it does and the file move
  puts it with other similar functions. Done in preparation for future
  cleanups. No functional differences intended.
