In debugging user problems with ip address/DNS issues with
smb3 mounts, we sometimes needed additional info on the hostname
and ip address.
Add two tracepoints, one to show socket connection success
and one for failures to connect to the socket.
Sample output:
mount.cifs-14551 [005] ..... 7636.547906: smb3_connect_done: conn_id=0x1 server=localhost addr=127.0.0.1:445

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.
