[ Upstream commit e52750fb1458ae9ea5860a08ed7a149185bc5b97 ]
When printing a dynamic array in a trace event, the method is rather ugly.
It has the format of:
__print_array(__get_dynamic_array(array),
__get_dynmaic_array_len(array) / el_size, el_size)
Since dynamic arrays are known to the tracing infrastructure, create a
helper macro that does the above for you.
__print_dynamic_array(array, el_size)
Which would expand to the same output.

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.
