-/**
- * @file
- *
- * @brief PVTCP socket destructor shim.
- *
- * The module reference accounting code for socket destruction in the core
- * Linux kernel does not know about PVTCP sockets, so it does not properly
- * increment/decrement the reference count on pvtcpkm when calling through a
- * function pointer into our destructor. If a module unload is requested on
- * pvtcpkm while a socket is being destroyed, it is possible for the destructor
- * to be preempted after decrementing the module reference count but before
- * returning to the core kernel. If the module code is unmapped before the
- * function return, it is possible that we will attempt to execute unmapped
- * code, resulting in a host crash.
- *
- * This shim proxies socket destruction requests through to the PVTCP socket
- * destructor, then jumps directly to module_put to drop the reference count.
- * module_put will return directly to the caller, eliminating the race.
