  Modified files:
    sys/fs/msdosfs       msdosfs_vfsops.c 
    sys/gnu/fs/ext2fs    ext2_vfsops.c 
    sys/kern             vfs_mount.c 
  Log:
  On 6.x this works:
  
  % mount | grep home
  /dev/ad4s1e on /home (ufs, local, noatime, soft-updates)
  % mount -u -o atime /home
  % mount | grep home
  /dev/ad4s1e on /home (ufs, local, soft-updates)
  
  Restore this behavior for on 7.x for the following mount options:
  noatime, noclusterr, noclusterw, noexec, nosuid, nosymfollow
  
  In addition, on 7.x, the following are equivalent:
  mount -u -o atime /home
  mount -u -o nonoatime /home
  
  Ideally, when we introduce new mount options, we should avoid
  options starting with "no". :)
