[ Upstream commit898374fdd7] When a listener is added, a part of creation of transport also registers program/port with rpcbind. However, when the listener is removed, while transport goes away, rpcbind still has the entry for that port/type. When deleting the transport, unregister with rpcbind when appropriate. ---v2 created a new xpt_flag XPT_RPCB_UNREG to mark TCP and UDP transport and at xprt destroy send rpcbind unregister if flag set.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
