The conversion itself is simple: add a markup for the title of this file and add markups for both tables. Yet, the big table here with IOCTL numbers is badly formatted: on several lines, the "Include File" column has some values that are bigger than the reserved space there. Also, on several places, a comment was misplaced at the "Include File" space. So, most of the work here is to actually ensure that each field will be properly fixed. Also worth to mention that some URLs have the asterisk character on it. Well, Sphinx has an issue with asterisks in the middle of an string. As this is URL, use the alternate format: %2A. As a side effect of this patch, it is now a lot easier to see that some reserved ioctl numbers are missing the include files where it is supposed to be used. PS.: While this is part of a subdir, I opted to convert this single file alone, as this file has a potential of conflicts, as most subsystem maintainers touch it.

Linux Kernel patch submission checklist
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Here are some basic things that developers should do if they want to see their
|
|
kernel patch submissions accepted more quickly.
|
|
|
|
These are all above and beyond the documentation that is provided in
|
|
:ref:`Documentation/process/submitting-patches.rst <submittingpatches>`
|
|
and elsewhere regarding submitting Linux kernel patches.
|
|
|
|
|
|
1) If you use a facility then #include the file that defines/declares
|
|
that facility. Don't depend on other header files pulling in ones
|
|
that you use.
|
|
|
|
2) Builds cleanly:
|
|
|
|
a) with applicable or modified ``CONFIG`` options ``=y``, ``=m``, and
|
|
``=n``. No ``gcc`` warnings/errors, no linker warnings/errors.
|
|
|
|
b) Passes ``allnoconfig``, ``allmodconfig``
|
|
|
|
c) Builds successfully when using ``O=builddir``
|
|
|
|
3) Builds on multiple CPU architectures by using local cross-compile tools
|
|
or some other build farm.
|
|
|
|
4) ppc64 is a good architecture for cross-compilation checking because it
|
|
tends to use ``unsigned long`` for 64-bit quantities.
|
|
|
|
5) Check your patch for general style as detailed in
|
|
:ref:`Documentation/process/coding-style.rst <codingstyle>`.
|
|
Check for trivial violations with the patch style checker prior to
|
|
submission (``scripts/checkpatch.pl``).
|
|
You should be able to justify all violations that remain in
|
|
your patch.
|
|
|
|
6) Any new or modified ``CONFIG`` options do not muck up the config menu and
|
|
default to off unless they meet the exception criteria documented in
|
|
``Documentation/kbuild/kconfig-language.rst`` Menu attributes: default value.
|
|
|
|
7) All new ``Kconfig`` options have help text.
|
|
|
|
8) Has been carefully reviewed with respect to relevant ``Kconfig``
|
|
combinations. This is very hard to get right with testing -- brainpower
|
|
pays off here.
|
|
|
|
9) Check cleanly with sparse.
|
|
|
|
10) Use ``make checkstack`` and ``make namespacecheck`` and fix any problems
|
|
that they find.
|
|
|
|
.. note::
|
|
|
|
``checkstack`` does not point out problems explicitly,
|
|
but any one function that uses more than 512 bytes on the stack is a
|
|
candidate for change.
|
|
|
|
11) Include :ref:`kernel-doc <kernel_doc>` to document global kernel APIs.
|
|
(Not required for static functions, but OK there also.) Use
|
|
``make htmldocs`` or ``make pdfdocs`` to check the
|
|
:ref:`kernel-doc <kernel_doc>` and fix any issues.
|
|
|
|
12) Has been tested with ``CONFIG_PREEMPT``, ``CONFIG_DEBUG_PREEMPT``,
|
|
``CONFIG_DEBUG_SLAB``, ``CONFIG_DEBUG_PAGEALLOC``, ``CONFIG_DEBUG_MUTEXES``,
|
|
``CONFIG_DEBUG_SPINLOCK``, ``CONFIG_DEBUG_ATOMIC_SLEEP``,
|
|
``CONFIG_PROVE_RCU`` and ``CONFIG_DEBUG_OBJECTS_RCU_HEAD`` all
|
|
simultaneously enabled.
|
|
|
|
13) Has been build- and runtime tested with and without ``CONFIG_SMP`` and
|
|
``CONFIG_PREEMPT.``
|
|
|
|
16) All codepaths have been exercised with all lockdep features enabled.
|
|
|
|
17) All new ``/proc`` entries are documented under ``Documentation/``
|
|
|
|
18) All new kernel boot parameters are documented in
|
|
``Documentation/admin-guide/kernel-parameters.rst``.
|
|
|
|
19) All new module parameters are documented with ``MODULE_PARM_DESC()``
|
|
|
|
20) All new userspace interfaces are documented in ``Documentation/ABI/``.
|
|
See ``Documentation/ABI/README`` for more information.
|
|
Patches that change userspace interfaces should be CCed to
|
|
linux-api@vger.kernel.org.
|
|
|
|
21) Check that it all passes ``make headers_check``.
|
|
|
|
22) Has been checked with injection of at least slab and page-allocation
|
|
failures. See ``Documentation/fault-injection/``.
|
|
|
|
If the new code is substantial, addition of subsystem-specific fault
|
|
injection might be appropriate.
|
|
|
|
23) Newly-added code has been compiled with ``gcc -W`` (use
|
|
``make EXTRA_CFLAGS=-W``). This will generate lots of noise, but is good
|
|
for finding bugs like "warning: comparison between signed and unsigned".
|
|
|
|
24) Tested after it has been merged into the -mm patchset to make sure
|
|
that it still works with all of the other queued patches and various
|
|
changes in the VM, VFS, and other subsystems.
|
|
|
|
25) All memory barriers {e.g., ``barrier()``, ``rmb()``, ``wmb()``} need a
|
|
comment in the source code that explains the logic of what they are doing
|
|
and why.
|
|
|
|
26) If any ioctl's are added by the patch, then also update
|
|
``Documentation/ioctl/ioctl-number.rst``.
|
|
|
|
27) If your modified source code depends on or uses any of the kernel
|
|
APIs or features that are related to the following ``Kconfig`` symbols,
|
|
then test multiple builds with the related ``Kconfig`` symbols disabled
|
|
and/or ``=m`` (if that option is available) [not all of these at the
|
|
same time, just various/random combinations of them]:
|
|
|
|
``CONFIG_SMP``, ``CONFIG_SYSFS``, ``CONFIG_PROC_FS``, ``CONFIG_INPUT``, ``CONFIG_PCI``, ``CONFIG_BLOCK``, ``CONFIG_PM``, ``CONFIG_MAGIC_SYSRQ``,
|
|
``CONFIG_NET``, ``CONFIG_INET=n`` (but latter with ``CONFIG_NET=y``).
