The verbose/debug logging done for `cat $MNT/dynamic_debug/control` is voluminous (2 per control file entry + 2 per PAGE). Moreover, it just prints pointer and sequence, which is not useful to a dyndbg user. So just drop them. Also require verbose>=2 for several other debug printks that are a bit too chatty for typical needs; ddebug_change() prints changes, once per modified callsite. Since queries like "+p" will enable ~2300 callsites in a typical laptop, a user probably doesn't need to see them often. ddebug_exec_queries() still summarizes with verbose=1. ddebug_(add|remove)_module() also print 1 line per action on a module, not needed by typical modprobe user. This leaves verbose=1 better focussed on the >control parsing process.

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.
