sys/dev/vn vn.c
Log:
Clean up properly when a `vn' module is kldunloaded to avoid panics
later. We now call cdesw_remove() to unregister the device, NULL
out any pointers to the vn_softc that exist in dev_t `si_drv1'
fields, and perform a destroy_dev() corresponding to the initial
make_dev().
This is not an MFC; vn(4) is no longer in -current.
