This test prevents code from being aligned around the : for easy visual counting of bitfield lengths. ie: int foo : 1, int bar : 2, int foobar :29; should be acceptable so remove the test. Signed-off-by:

Currently the parenthesis alignment test works only on misalignments of if statements like if (foo(bar, baz) Expand the test to find misalignments like: static inline int foo(int bar, int baz) and foo(bar, baz); and foo = bar(baz, qux); Expand the $Inline keyword for __inline and __inline__ too. Add $Inline to $Declare so it also matches "static inline <foo>". These checks are only performed with --strict. Signed-off-by:

A commit hook for the Gerrit code review server [1] inserts change identifiers so Gerrit can track patches through multiple revisions. These identifiers are noise in the context of the upstream kernel. (Many Gerrit servers are private. Even given a public instance, given only a Change-Id, one must guess which server a change was tracked on. Patches submitted to the Linux kernel mailing lists should be able to stand on their own. If it's truly useful to reference code review on a Gerrit server, a URL is a much clearer way to do so.) Thus, issue an error when a Change-Id line is encountered before the Signed-off-by. 1. https://gerrit.googlesource.com/gerrit/+/master/gerrit-server/src/main/resources/com/google/gerrit/server/tools/root/hooks/commit-msgSigned-off-by:

Revert commit 7e4915e7 ("checkpatch: add warning of future __GFP_NOFAIL use"). There are no plans to remove __GFP_NOFAIL. __GFP_NOFAIL exists to a) centralise the retry-allocation-for-ever operation into the core allocator, which is the appropriate implementation site and b) permit us to identify code sites which aren't handling memory exhaustion appropriately.

Networking prefers this style, so warn when it's not used. Networking uses: void foo(int bar) { int baz; code... } not void foo(int bar) { int baz; code... } There are a limited number of false positives when using macros to declare variables like: WARNING: networking uses a blank line after declarations #330: FILE: net/ipv4/inet_hashtables.c:330: + int dif = sk->sk_bound_dev_if; + INET_ADDR_COOKIE(acookie, saddr, daddr) Signed-off-by: -

Florian Vaussard authored
With a compatible string like compatible = "foo"; checkpatch will currently try to find "foo" in vendor-prefixes.txt, which is wrong since the vendor prefix is empty in this specific case. Skip the vendor test if the compatible is not like compatible = "vendor,something"; Signed-off-by:

The current octal permissions test is very slow. When patch ("checkpatch: add checks for constant non-octal permissions") was added, processing time approximately tripled. Regain almost all of the performance by not looping through all the possible functions unless the line contains one of the functions. Signed-off-by: -

This test is a bit noisy and opinions seem to agree that it should not warn in a lot more situations. It seems people agree that: return (foo || bar); and return foo || bar; are both acceptable style and checkpatch should be silent about them. For now, it warns on parentheses around a simple constant or a single function or a ternary. return (foo); return (foo(bar)); return (foo ? bar : baz); The last ternary test may be quieted in the future. Modify the deparenthesize function to only strip balanced leading and trailing parentheses. Signed-off-by:

It's very common to have normal block comments for the initial comments of a file description preface. So for files in drivers/net and net/ don't emit a warning when the first comment block in the file uses the normal block comment style and not the networking block comment style. Signed-off-by:

static const char* arrays create smaller text as each function call does not have to populate the array. Emit a warning when char *arrays aren't static const and the array is not apparently global by being declared in the first column. Signed-off-by:

checkpatch could not distinguish between a variable in a struct named jiffies and the normal jiffies. foo->jiffies would emit a "Comparing jiffies" arning. Update the $Compare variable to do a negative look-behind for "-" when finding a ">" so that a pointer dereference like -> isn't a comparison. Signed-off-by:

Emit a warning when using any of these __constant_<foo> forms: __constant_cpu_to_be[x] __constant_cpu_to_le[x] __constant_be[x]_to_cpu __constant_le[x]_to_cpu __constant_htons __constant_ntohs Using any of these outside of include/uapi/ isn't preferred as using the function without __constant_ is identical when the argument is a constant.

umode_t permissions are sometimes mistakenly written with decimal constants. Verify that numeric permissions are using octal. Add a list of the most commonly used functions and macros that have umode_t permissions and the argument position. Add a $Octal type to $Constant. Allow $LvalOrFunc to be a pointer indirection too.

Holger reported: : The macro udelay cannot handle large values because of loss-of-precision. : : IMHO udelay on ARM is broken, because it also cannot work with fast : ARM processors (where bogomips >= 3355, which is in sight now). It's : just not broken enough that someone did something against it ... so : the current kludge is good enough. Until then, warn on long udelay uses. Also fix uses of $line that should have been $herecurr. Signed-off-by:

Include appropriate header file include/linux/decompress/inflate.h in lib/decompress_inflate.c because it has prototype declaration of function defined in lib/decompress_inflate.c. Also, fix the guard around the header file include/linux/decompress/inflate.h to use a more unique guard symbol. This avoids conflict with the INFLATE_H defined by zlib_inflate/inflate.h. This eliminates the following warning in lib/decompress_inflate.c: lib/decompress_inflate.c:35:17: warning: no previous prototype for `gunzip' [-Wmissing-prototypes] Signed-off-by:

These are just some very minor and misc cleanups in the PRNG. In prandom_u32() we store the result in an unsigned long which is unnecessary as it should be u32 instead that we get from prandom_u32_state(). prandom_bytes_state()'s comment is in kdoc format, so change it into such as it's done everywhere else. Also, use the normal comment style for the header comment. Last but not least for readability, add some newlines. Signed-off-by:

Having a discussion about sparse warnings in the kernel, and that we should clean them up, I decided to pick a random file to do so. This happened to be devres.c which gives the following warnings: CHECK lib/devres.c lib/devres.c:83:9: warning: cast removes address space of expression lib/devres.c:117:31: warning: incorrect type in return expression (different address spaces) lib/devres.c:117:31: expected void [noderef] <asn:2>* lib/devres.c:117:31: got void * lib/devres.c:125:31: warning: incorrect type in return expression (different address spaces) lib/devres.c:125:31: expected void [noderef] <asn:2>* lib/devres.c:125:31: got void * lib/devres.c:136:26: warning: incorrect type in assignment (different address spaces) lib/devres.c:136:26: expected void [noderef] <asn:2>*[assigned] dest_ptr lib/devres.c:136:26: got void * lib/devres.c:226:9: warning: cast removes address space of expression Mostly it's just the use of typecasting to void * without adding __force, or returning ERR_PTR(-ESOMEERR) without typecasting to a __iomem type. I added a helper macro IOMEM_ERR_PTR() that does the typecast to make the code a little nicer than adding ugly typecasts to the code.
