checkpatch: Warn on improper usage of Co-developed-by

2019-03-25T16:44:43Z

The purpose of Co-developed-by: is to give attribution to authors who aren't already attributed by the From: tag, i.e. who aren't the nominal patch author. Because Co-developed-by: is essentially a variation of From:, it must be accompanied by a Signed-off-by: of the associated co-author. To ease the burden of determining whether or not co-authors have signed off, Co-developed-by and Signed-off-by: must be explicitly paired, i.e. on consecutive lines for a given co-author.

checkpatch: allow reporting C99 style comments

2019-03-08T02:32:01Z

Presently C99 style comments are removed unconditionally before actual patch validity check happens. This is a problem for some third party projects which use checkpatch.pl but do not allow C99 style comments. This patch adds yet another variable, named C99_COMMENT_TOLERANCE. If it is included in the --ignore command line or config file options list, C99 comments in the patch are reported as errors. Tested by processing a patch with a C99 style comment, it passes the check just fine unless '--ignore C99_COMMENT_TOLERANCE' is present in .checkpatch.conf.

checkpatch: add some new alloc functions to various tests

2019-03-08T02:32:01Z

Many new generic allocation functions like the kvmalloc family have been added recently to the kernel. The allocation functions test now includes: o kvmalloc and variants o kstrdup_const o kmemdup_nul o dma_alloc_coherent o alloc_skb and variants Add a separate $allocFunctions variable to help make the allocation functions test a bit more readable. Miscellanea: o Use $allocFunctions in the unnecessary OOM message test and add exclude uses with __GFP_NOWARN o Use $allocFunctions in the unnecessary cast test o Add the kvmalloc family to the preferred sizeof alloc style foo = kvmalloc(sizeof(*foo), ...)

checkpatch: verify SPDX comment style

2019-03-08T02:32:00Z

Using SPDX commenting style // or /* is specified for various file types in Documentation/process/license-rules.rst so add an appropriate test for .[chsS] files because many proposed file additions and patches do not use the correct style.

coding-style: Clarify the expectations around bool

2019-01-21T02:07:39Z

There has been some confusion since checkpatch started warning about bool use in structures, and people have been avoiding using it. Many people feel there is still a legitimate place for bool in structures, so provide some guidance on bool usage derived from the entire thread that spawned the checkpatch warning.
