Steve French 020eec5f71 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.
