checkpatch: Warn on code with 6+ tab indentation
Overly indented code should be refactored.
Suggest refactoring excessive indentation of of
if/else/for/do/while/switch statements.
For example:
$ cat t.c
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char **argv)
{
if (1)
if (2)
if (3)
if (4)
if (5)
if (6)
if (7)
if (8)
;
return 0;
}
$ ./scripts/checkpatch.pl -f t.c
WARNING: Too many leading tabs - consider code refactoring
#12: FILE: t.c:12:
+ if (6)
WARNING: Too many leading tabs - consider code refactoring
#13: FILE: t.c:13:
+ if (7)
WARNING: Too many leading tabs - consider code refactoring
#14: FILE: t.c:14:
+ if (8)
