Hi,
I wanted to submit my first patch.
But I have some confusion about the /scripts/checkpatch.pl errors.
After correcting some checkpatch errors, when I run checkpatch.pl, it showed me 0 errors.
But when I create patches are git format-patch, it is showing me 1 error.
If I fix error in patch, it showed me back again in files.
Now, I am confused which error to fix while submitting patches, the file or the patch errors.
Please provide your opinion.
File: mm/page_alloc.c
Previous file errors:
total: 16 errors, 110 warnings, 6255 lines checked
After fixing errors:
total: 0 errors, 105 warnings, 6255 lines checked
And, after running on patch:
ERROR: need consistent spacing around '*' (ctx:WxV)
#153: FILE: mm/page_alloc.c:5476:
+int min_free_kbytes_sysctl_handler(ctl_table *table, int write,

did you run the checkpatch.pl on the file which gets created
after git format-patch?
If yes, then I think it is not necessary.You can use git-am to apply
your own patch on a undisturbed file and if it applies properly then
you are good to go i.e. you can send your patch.

Yes, first I ran checkpatch directly on the file(mm/page_alloc.c) and fixed all the errors.
It showed me (0) errors.
Then I created a patch using _git format-patch_ and ran checkpatch again on the created patch.
But now it is showing me 1 error.
According to me this error is false positive (irrelevant), because I did not change anything related to the error and also the similar change already exists somewhere else too.
Do you mean, shall I go ahead and submit the patch with this 1 error??

Rather a shot into the dark, but it looks like checkpatch is
misinterpreting 'ctl_table' as an arithmetic operand instead of a type.
I don't know how checkpatch learns about types created by typedefs, but
my guess is, that this line
typedef struct ctl_table ctl_table; (include/linux/sysctl.h)
is not correctly picked up by checkpatch.
So, I assume this actually is a false positive.

checkpatch isn't a c compiler.
It assumes any <foo>_t is a typedef.

Yup.
Maybe this would work?

Another option is to use "struct ctl_table" instead of bare ctl_table.
