Add a ftrace2bconf.sh under tools/bootconfig/scripts which generates a bootconfig file from the current ftrace settings. To read the ftrace settings, ftrace2bconf.sh requires the root privilege (or sudo). The ftrace2bconf.sh will output the bootconfig to stdout and error messages to stderr, so usually you'll run it as # ftrace2bconf.sh > ftrace.bconf Note that some ftrace configurations are not supported. For example, function-call/callgraph trace/notrace settings are not supported because the wildcard has been expanded and lost in the ftrace anymore.

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.
