  "message": "tun: Fix device unregister race\n\nIt is currently possible for an asynchronous device unregister\nto cause the same tun device to be unregistered twice.  This\nis because the unregister in tun_chr_close only checks whether\n__tun_get(tfile) !\u003d NULL.  This however has nothing to do with\nwhether the device has already been unregistered.  All it tells\nyou is whether __tun_detach has been called.\n\nThis patch fixes this by using the most obvious thing to test\nwhether the device has been unregistered.\n\nIt also moves __tun_detach outside of rtnl_unlock since nothing\nthat it does requires that lock.\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nSigned-off-by: David S. Miller \u003cdavem@davemloft.net\u003e\n",
