kernel patches.
-1: Builds cleanly with applicable or modified CONFIG options =y, =m, and
+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 with applicable or modified CONFIG options =y, =m, and
=n. No gcc warnings/errors, no linker warnings/errors.
-2: Passes allnoconfig, allmodconfig
+2b: Passes allnoconfig, allmodconfig
+
+2c: Builds successfully when using O=builddir
3: Builds on multiple CPU architectures by using local cross-compile tools
- or something like PLM at OSDL.
+ 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.
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.
+ 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_LBD.
+ CONFIG_LBDAF.
15: All codepaths have been exercised with all lockdep features enabled.
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'.
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)
