Currently mbps knob could only be set once before switching power knob to on, after power knob has been set at least once, there is no way to set mbps knob again due to -EBUSY. As nullb is mainly used for testing, in order to make it flexible, this removes the flag NULLB_DEV_FL_CONFIGURED so that mbps knob can be reset when power knob is off, e.g. echo 0 > /config/nullb/a/power echo 40 > /config/nullb/a/mbps echo 1 > /config/nullb/a/power So does other knobs under /config/nullb/a.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
