I'm guessing that this\nwas done to allow creating psocks for non-inet sockets.\n\nUnfortunately the destruction path for psock includes the ULP\nunwind, so we need to fail the sk_psock_init() itself.\nOtherwise if ULP is already present we'll notice that later,\nand call tcp_update_ulp() with the sk_proto of the ULP\nitself, which will most likely result in the ULP looping\nits callbacks."
