This patch adds the resource name to dlm tracepoints. The name usually comes through the lkb_resource, but in some cases a resource may not yet be associated with an lkb, in which case the name and namelen parameters are used. It should be okay to access the lkb_resource and the res_name field at the time when the tracepoint is invoked. The resource is assigned to a lkb and it's reference is being held during the tracepoint call. During this time the resource cannot be freed. Also a lkb will never switch its assigned resource. The name of a dlm_rsb is assigned at creation time and should never be changed during runtime as well. The TP_printk() call uses always a hexadecimal string array representation for the resource name (which is not necessarily ascii.)

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.
