So, I assume you have a directory named 'b' in the kernel-root-dir?

The p1-detection is heuristic and can always be fooled, so I don't think
extending the logic will help. If too many users think it is annoying,
it may be better to remove it. I do think, however, that it might help
users sending in their first patches, so I'd prefer to keep it.
Experienced users have the option to use something like "--ignore
PATCH_PREFIX" in their .checkpatch.conf. I vote for improving the error
message but won't oppose a removal if that is what is wanted.

Regards,

   Wolfram
