mainlining shenanigans
b72acf4501
The current listening_get_next() is overloaded by passing NULL to the 2nd arg, like listening_get_next(seq, NULL), to mean get_first(). This patch moves some logic from the listening_get_next() into a new function listening_get_first(). It will be equivalent to the current established_get_first() and established_get_next() setup. get_first() is to find a non empty bucket and return the first sk. get_next() is to find the next sk of the current bucket and then resorts to get_first() if the current bucket is exhausted. The next patch is to move the listener seq_file iteration from listening_hash (port only) to lhash2 (port+addr). Separating out listening_get_first() from listening_get_next() here will make the following lhash2 changes cleaner and easier to follow.

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.
