  SVN rev 183070 on 2008-09-16 10:59:35Z by kib
  
  When downgrading the read-write mount to read-only, do_unmount() sets
  MNT_RDONLY flag before the VFS_MOUNT() is called. In ufs_inactive()
  and ufs_itimes_locked(), UFS verifies whether the fs is read-only by
  checking MNT_RDONLY, but this may cause loss of the IN_MODIFIED flag
  for inode on the fs being remounted rw->ro.
  
  Introduce UFS_RDONLY() struct ufsmount' method that reports the value
  of the fs_ronly. The later is set to 1 only after the remount is
  finished.
