[ Upstream commit f61bca58f6 ]
Commit <26d92e951fe0>
("net/smc: move unhash as early as possible in smc_release()")
fixes one occurrence in the smc code, but the same pattern exists
in other places. This patch covers the remaining occurrences and
makes sure, the unhash operation is done before the smc->clcsock is
released. This avoids a potential use-after-free in smc_diag_dump().

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
