sock_unregister: remove a protocol handler
sock_unregister - remove a protocol handler
- protocol family to remove
This function is called by a protocol handler that wants to remove its address family, and have it unlinked from the new socket creation.
If protocol handler is a module, then it can use module reference counts to protect against new references. If protocol handler is not a module then it needs to provide its own protection in the ops->create routine.
