Add the "D:" type which behaves the same as "K:" but will only match content present in a patch file.
To illustrate: Imagine this entry in MAINTAINERS: NEW REPUBLIC M: Han Solo <hans...@rebelalliance.co> W: https://www.jointheresistance.org D: \bstrncpy\b Our maintainer, Han, will only be added to the recipients if a patch file is passed to get_maintainer (like what b4 does): $ ./scripts/get_maintainer.pl 0004-some-change.patch If the above patch has a `strncpy` present in the subject, commit log or diff then Han will be to/cc'd. However, in the event of a file from the tree given like: $ ./scripts/get_maintainer.pl ./lib/string.c Han will not be noisily to/cc'd (like a K: type would in this circumstance) Signed-off-by: Justin Stitt <justinst...@google.com> --- MAINTAINERS | 5 +++++ scripts/get_maintainer.pl | 12 ++++++++++-- 2 files changed, 15 insertions(+), 2 deletions(-) diff --git a/MAINTAINERS b/MAINTAINERS index b19995690904..94e431daa7c2 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -59,6 +59,11 @@ Descriptions of section entries and preferred order matches patches or files that contain one or more of the words printk, pr_info or pr_err One regex pattern per line.
