Don't depend on other header files pulling in ones + that you use. + +2: Builds cleanly with applicable or modified CONFIG options =y, =m, and + =n. No gcc warnings/errors, no linker warnings/errors. + +2b: Passes allnoconfig, allmodconfig + +2c: 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 + Documentation/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 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_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_HOTPLUG, CONFIG_MAGIC_SYSRQ, + CONFIG_NET, CONFIG_INET=n (but latter with CONFIG_NET=y) -- cgit v1.2.3
