OK, granted. But this is dummy code, and this is not what I'd expect checkpatch.pl to check for. > or something, the first for is at the wrong level of indentation and the > second for is at the wrong level of indentation relative to the first one. If someone writes the code this way, the problem is usually not the indentation that is most likely correct, but the fact that the code does something completely different from what the author thought it would do. We already had such bugs in the kernel, they are unlikely to be spotted at code review, but for a script that looks at the source code they should be easy to spot. cu Adrian -- "Is there not promise of rain?"
