[ Upstream commit21cbd90a6f] __inet_hash_connect() has a fast path taken if sk_head(&tb->owners) is equal to the sk parameter. sk_head() returns the hlist_entry() with respect to the sk_node field. However entries in the tb->owners list are inserted with respect to the sk_bind_node field with sk_add_bind_node(). Thus the check would never pass and the fast path never execute. This fast path has never been executed or tested as this bug seems to be present since commit1da177e4c3("Linux-2.6.12-rc2"), thus remove it to reduce code complexity.

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.
