New Revision: 268784
URL: http://svnweb.freebsd.org/changeset/base/268784

Log:
  MFC	r268628, r268631, r268635:
  
  Convert *rootDir from external to static.
  
  fsck_msdosfs: be a bit more permissive.
  
  The free space value in the FSInfo block is merely unitialized when it is
  0xffffffff. This fixes a bug found in NetBSD.
  
  Respect FSFIXFAT.
  
  Fix some whitespace issues while here.
  
  Obtained from:	NetBSD (CVS rev. 1.22, rev. 1.9), OpenBSD (misc)
