net/smc: Introduce tracepoint for fallback
This introduces tracepoint for smc fallback to TCP, so that we can track which connection and why it fallbacks, and map the clcsocks' pointer with /proc/net/tcp to find more details about TCP connections. Compared with kprobe or other dynamic tracing, tracepoints are stable and easy to use.

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.
