smb3: add tracepoint for slow responses
If responses take longer than one second from the server, we can optionally log them to dmesg in current cifs.ko code (CONFIG_CIFS_STATS2 must be configured and a /proc/fs/cifs/cifsFYI flag must be set), but can be more useful to log these via ftrace (tracepoint is smb3_slow_rsp) which is easier and more granular (still requires CONFIG_CIFS_STATS2 to be configured in the build though).

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. See Documentation/00-INDEX for a list of what is contained in each file. 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.
