  Modified files:
    sys/netsmb           smb_dev.c 
  Log:
  It turns out that devfs_close() does a dev_refthread() before invoking
  device specific d_close(), which makes subsequent destroy_dev() being
  blocked in the "devdrn" loop.
  
  This bandaid should fix the smbfs hang/crashing observed on -CURRENT since
  the introduction of sys/kern/kern_conf.c:1.199:
  
          # mount_smbfs -I server //server/share /mnt
          Password:
          [hang]
