The buffer size histograms in smc_stats, namely rx/tx_rmbsize, record the sizes of ringbufs for all connections that have ever appeared in the net namespace. They are incremental and we cannot know the actual ringbufs usage from these. So here introduces statistics for current ringbufs usage of existing smc connections in the net namespace into smc_stats, it will be incremented when new connection uses a ringbuf and decremented when the ringbuf is unused.

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 reStructuredText 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.
