sockmap and sockhash don't have something in common in allocation, so let's
introduce different helpers to calculate their memory usage.
The reuslt as follows,
- before
28: sockmap name count_map flags 0x0
key 4B value 4B max_entries 65536 memlock 524288B
29: sockhash name count_map flags 0x0
key 4B value 4B max_entries 65536 memlock 524288B
- after
28: sockmap name count_map flags 0x0
key 4B value 4B max_entries 65536 memlock 524608B
29: sockhash name count_map flags 0x0 <<<< no updated elements
key 4B value 4B max_entries 65536 memlock 1048896B

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.
