For the upcoming 'define the _ddebug descriptor in assembly', we need all the descriptors in a translation unit to have distinct names (because asm does not understand C scope). The easiest way to achieve that is as usual with an extra level of macros, passing the identifier to use to the innermost macro, generating it via __UNIQUE_ID or something. However, instead of repeating that exercise for dynamic_pr_debug, dynamic_dev_dbg, dynamic_netdev_dbg and dynamic_hex_dump separately, we can use the similarity between their bodies to implement them via a common macro, _dynamic_func_call - though the hex_dump case requires a slight variant, since print_hex_dump does not take the _ddebug descriptor. We'll also get to use that variant elsewhere (btrfs).

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.
