The kernel-abi directive passes its argument straight to the shell. This is unfortunate and unnecessary. Let's always use paths relative to $srctree/Documentation/ and use subprocess.check_call() instead of subprocess.Popen(shell=True). This also makes the code shorter.

|
|
|
|
The ``kernel-abi`` (:py:class:`KernelCmd`) directive calls the
|
|
scripts/get_abi.pl script to parse the Kernel ABI files.
|
|
|
|
Overview of directive's argument and options.
|
|
|
|
.. code-block:: rst
|
|
|
|
.. kernel-abi:: <ABI directory location>
|
|
:debug:
|
|
|
|
The argument ``<ABI directory location>`` is required. It contains the
|
|
location of the ABI files to be parsed.
|
|
|
|
``debug``
|
|
Inserts a code-block with the *raw* reST. Sometimes it is helpful to see
|
|
what reST is generated.
