Hello, As part of the eudyptula challenge I submitted a coding style patch on staging (that you can find here: https://lkml.org/lkml/2017/4/28/148) I had read beforehand the submission guidelines, but I still have some questions which I think are more appropriate posted here than as an answer to the patch thread: - the patch is clear with "checkpatch.pl --strict", but there are some tabs in the middle of the line. In my editor and apparently with checkpatch.pl those tabs are used for alignment (so spend less than 8 characters) so that the total of the line in less than 80 characters. In the submitted patch however, due to the +- at the beginning of the line they appear larger and thus the line in more than 80 character. My question is: Should I consider the patch clean or interpret the guideline "tabs are 8 characters" strictly (and not tabs "at the beginning on the line" are 8 characters)? - when I make modification to the patch message but not the diff lines, should I still increment the patch version, or rather maybe resend it with something like RESEND in the subject? Sorry if these are written in the doc, I reread it but couldn't find clear answers (and sorry to Greg Kroah-Hartma who has to read my dumb submissions both here and in the kernel mailing list). Thank you, Michael Mera
