docs-rst: add documents to development-process
Add several documents to the development-process ReST book. As we don't want renames, use symlinks instead, keeping those documents on their original place. Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

-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/SubmittingPatches <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/CodingStyle <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 don't muck up the config menu.
-
-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.``
-
-14) If the patch affects IO/Disk, etc: has been tested with and without
- ``CONFIG_LBDAF.``
-
-15) All codepaths have been exercised with all lockdep features enabled.
-
-16) All new ``/proc`` entries are documented under ``Documentation/``
-
-17) All new kernel boot parameters are documented in
- ``Documentation/kernel-parameters.txt``.
-
-18) All new module parameters are documented with ``MODULE_PARM_DESC()``
-
-19) 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.
-
-20) Check that it all passes ``make headers_check``.
-
-21) 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.
-
-22) 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".
-
-23) 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.
-
-24) 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.
-
-25) If any ioctl's are added by the patch, then also update
- ``Documentation/ioctl/ioctl-number.txt``.
-
-26) 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``).
