| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Usage of these flags has been deprecated for nearly 4 years by: commit f77bf01425b11947eeb3b5b54685212c302741b8 Author: Sam Ravnborg <sam@neptun.(none)> Date: Mon Oct 15 22:25:06 2007 +0200 kbuild: introduce ccflags-y, asflags-y and ldflags-y Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command line use. By default, gmake(1) do not override command line setting, so this is likely to result in build failure or unexpected behavior. Warn about their introduction in Makefile or Kbuild files.

* | checkpatch: add a --strict check for utf-8 in commit logsJoe Perches2011-10-311-4/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some find using utf-8 in commit logs inappropriate. Some patch commit logs contain unintended utf-8 characters when doing things like copy/pasting compilation output. Look for the start of any commit log by skipping initial lines that look like email headers and "From: " lines. Stop looking for utf-8 at the first signature line.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some users would like the ability to not emit some of the messages that checkpatch produces. This can make it easier to use checkpatch in other projects and integrate into scm hook scripts. Add command line option to "--ignore" various message types. Add option --show-types to emit the "type" of each message. Categorize all ERROR, WARN and CHK messages with types. Add optional .checkpatch.conf file to store default options. 3 paths are searched for .checkpatch.conf . customized per-tree configurations $HOME user global configuration when per-tree configs don't exist ./scripts lk defaults to override script The .conf file can contain any valid command-line argument and the contents are prepended to any additional command line arguments.

* checkpatch: suggest using min_t or max_tJoe Perches2011-07-251-0/+35
| | | | | | | | | | | | | | | | | | | | | | A common issue with min() or max() is using a cast on one or both of the arguments when using min_t/max_t could be better. Add cast detection to uses of min/max and suggest an appropriate use of min_t or max_t instead. Caveat: This only works for min() or max() on a single line. It does not find min() or max() split across multiple lines.

* scripts/checkpatch.pl: reset rpt_cleaners warningsMike Frysinger2011-03-221-0/+1
| | | | | | | | | | | | | | | | If you run checkpatch against multiple patches, and one of them has a whitespace issue which can be helped via a script (rpt_cleaners), you will see the same NOTE over and over for all subsequent patches. It makes it seem like those patches also have whitespace problems when in reality, there's only one or two bad apples. So reset rpt_cleaners back to 0 after we've issued the note so that it only shows up near the patch with the actual problems.

* kstrto*: converting strings to integers done (hopefully) rightAlexey Dobriyan2011-03-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. simple_strto*() do not contain overflow checks and crufty, libc way to indicate failure. 2. strict_strto*() also do not have overflow checks but the name and comments pretend they do. 3. Both families have only "long long" and "long" variants, but users want strtou8() 4. Both "simple" and "strict" prefixes are wrong: Simple doesn't exactly say what's so simple, strict should not exist because conversion should be strict by default. The solution is to use "k" prefix and add convertors for more types. Enter kstrtoull() kstrtoll() kstrtoul() kstrtol() kstrtouint() kstrtoint() kstrtou64() kstrtos64() kstrtou32() kstrtos32() kstrtou16() kstrtos16() kstrtou8() kstrtos8() Include runtime testsuite (somewhat incomplete) as well. strict_strto*() become deprecated, stubbed to kstrto*() and eventually will be removed altogether. Use kstrto*() in code today! Note: on some archs _kstrtoul() and _kstrtol() are left in tree, even if they'll be unused at runtime. This is temporarily solution, because I don't want to hardcode list of archs where these functions aren't needed. Current solution with sizeof() and __alignof__ at least always works.

* checkpatch: types may sit on a line on their ownAndy Whitcroft2010-10-261-1/+1
| | | | | | | | | | | | | | When the following form is used we have a type which fully fills a line. This means that a type may end at the end of line as well as at the following identifier. int ** foo; Reported-by: Daniel Walker <dwalker@fifo99.com> Signed-off-by: Andy Whitcroft <apw@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* checkpatch: fix regressions in "fix handling of leading spaces"Andy Whitcroft2010-10-261-3/+6
| | | | | | | | | | | | The patch "checkpatch: fix handling of leading spaces" added checks for leading spaces on lines, but this introduces regressions. Firstly it does not correctly detect when we are in a comment. Secondly it does not allow for preprocessor command spacing. Finally it does not allow for label indentation which is required to be less than one tab. Fix these up: Signed-off-by: Andy Whitcroft <apw@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* checkpatch: fix extraneous EXPORT_SYMBOL* warningsPatrick Pannuto2010-08-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These are caused by checkpatch incorrectly parsing its internal representation of a statement block for struct's (or anything else that is a statement block encapsulated in {}'s that also ends with a ';'). Fix this by properly parsing a statement block. An example: +struct dummy_type dummy = { + .foo = "baz", +}; +EXPORT_SYMBOL_GPL(dummy); + +static int dummy_func(void) +{ + return -EDUMMYCODE; +} +EXPORT_SYMBOL_GPL(dummy_func); WARNING: EXPORT_SYMBOL(foo); should immediately \ follow its function/variable #19: FILE: dummy.c:4: +EXPORT_SYMBOL_GPL(dummy); The above warning is issued when it should not be.

* checkpatch: warn about unexpectedly long msleep'sPatrick Pannuto2010-08-091-0/+7
| | | | | | | | | | | | As explained in Documentation/timers/timers-howto.txt, msleep's of < 20ms may sleep for as long as 20ms. Caller's of msleep(1) or msleep(2), etc are likely not to expect this quirky behavior - warn them.
