In order to support the get-lore-mbox.py tool described in [1], I ran:

git format-patch --base=<commit> --cover-letter <revrange>

...which generated a "base-commit: <commit-hash>" tag at the end of the
cover letter. However, checkpatch.pl generated an error upon encounting
"base-commit:" in the cover letter:

"ERROR: Please use git commit description style..."

...because it found the "commit" keyword, and failed to recognize that
it was part of the "base-commit" phrase, and as such, should not be
subjected to the same commit description style rules.

Update checkpatch.pl to include a special case for "base-commit:", so
that that tag no longer generates a checkpatch error.

As far as I can tell, we should be able to rely on that, yes.


I presume this should actually be

$line !~ /^base-commit:/ &&
or maybe
$line !~ /^\s*base-commit:/ &&

$line !~ /^\s*(?:Link|Patchwork|http|https|BugLink):/i &&

and probably better to just add it to this line instead like

$line !~ /^\s*(?:Link|Patchwork|http|https|BugLink|base-commit):/i &&

Yes, that looks nice. I'll send a v2 doing it that way.


thanks,
