Linux Kernel patch sumbittal 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
|
|
Documentation/SubmittingPatches and elsewhere regarding submitting Linux
|
|
kernel patches.
|
|
|
|
|
|
|
|
1: Builds cleanly with applicable or modified CONFIG options =y, =m, and
|
|
=n. No gcc warnings/errors, no linker warnings/errors.
|
|
|
|
2: Passes allnoconfig, allmodconfig
|
|
|
|
3: Builds on multiple CPU architectures by using local cross-compile tools
|
|
or something like PLM at OSDL.
|
|
|
|
4: ppc64 is a good architecture for cross-compilation checking because it
|
|
tends to use `unsigned long' for 64-bit quantities.
|
|
|
|
5: Matches kernel coding style(!)
|
|
|
|
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 kernel-doc to document global kernel APIs. (Not required for
|
|
static functions, but OK there also.) Use 'make htmldocs' or 'make
|
|
mandocs' to check the 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_SPINLOCK_SLEEP 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_LBD.
|
|
|
|
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.
|
|
|
|
20: Check that it all passes `make headers_check'.
|
|
|
|
21: Has been checked with injection of at least slab and page-allocation
|
|
fauilures. See Documentation/fault-injection/.
|
|
|
|
If the new code is substantial, addition of subsystem-specific fault
|
|
injection might be appropriate.
