Previous behavior allowed only alphabetic prefixes like pr_info to exceed
the 80 column line length limit.ath6kl wants to add a digit into the prefix, so allow numbers as well as
digits in the _ printks.__ratelimited and __once and WARN_RATELIMIT
and WARN_ONCE may now exceed 80 cols.Add missing _printk type for completeness.

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.
Multiple lines may be used, blank lines are ignored, # is a comment.Update "false positive" output for readability.
Update version to 0.32

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.This does find:
min((u32)foo, bar);
But it does not find:
max((unsigned long)foo,
bar);Suggested-by: Andrew Morton

Currently, printk lines with a only KERN_PREFIX and a quoted string
without a comma or close paren that exceed 80 columns are flagged with a
warning.ie:
printk(KERN_WARNING "some long string that extends beond 80 cols..."
"and is continued on another line\n");Allow this form instead of emitting a warning.

Because the second and third arguments of memset have the same type, it

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.Signed-off-by: Mike Frysinger

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.Signed-off-by: Alexey Dobriyan

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.
