    sys/conf             files 
    sys/fs/msdosfs       msdosfs_vfsops.c msdosfs_vnops.c 
  Log:
  Add a "-o large" mount option for msdosfs.  Convert compile-time checks for
  #ifdef MSDOSFS_LARGE to run-time checks to see if "-o large" was specified.
  
  Test case provided by Oliver Fromme:
    truncate -s 200G test.img
    mdconfig -a -t vnode -f test.img -u 9
    newfs_msdos -s 419430400 -n 1 /dev/md9 zip250
    mount -t msdosfs /dev/md9 /mnt    # should fail
    mount -t msdosfs -o large /dev/md9 /mnt   # should succeed
