checkpatch: warn about memset with swapped arguments

2011-03-23T00:44:15Z

Because the second and third arguments of memset have the same type, it turns out to be really easy to mix them up. This bug comes up time after time, so checkpatch should really be checking for it at patch submission time.

scripts/checkpatch.pl: reset rpt_cleaners warnings

2011-03-23T00:44:15Z

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) right

2011-03-23T00:44:14Z

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.pl: add "prefer __packed" check

checkpatch: check for world-writeable sysfs/debugfs files

2011-01-13T16:03:11Z

Exporting world writable sysfs/debugfs files is usually a bad thing. Warn about it. Signed-off-by: Dave Jones Cc: Andy Whitcroft Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

checkpatch.pl: fix CAST detection

2011-01-13T16:03:11Z

We should only claim that something is a cast if we did not encouter a token before, that did set av_pending. This fixes the operator * in the line below to be detected as binary (vs unary). kmalloc(sizeof(struct alphatrack_ocmd) * true_size, GFP_KERNEL); Reported-by: Audun Hoem Signed-off-by: Florian Mickler Cc: Andy Whitcroft Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

semaphore: Remove mutex emulation
