[ Upstream commitde8a6b15d9] Currently, we correlate the mctp_sk_key lifetime to the sock lifetime through the sock hash/unhash operations, but this is pretty tenuous, and there are cases where we may have a temporary reference to an unhashed sk. This change makes the reference more explicit, by adding a hold on the sock when it's associated with a mctp_sk_key, released on final key unref.

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 Restructured Text 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.
