Chuck Lever 2cde7f8118 NFSD: Add an nfsd_cb_lm_notify tracepoint
When the server kicks off a CB_LM_NOTIFY callback, record its
arguments so we can better observe asynchronous locking behavior.
For example:

            nfsd-998   [002]  1471.705873: nfsd_cb_notify_lock:  addr=192.168.2.51:0 client 6092a47c:35a43fc1 fh_hash=0x8950b23a

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.
