[PATCH] scripts: helper for mailing patches from git to the maintainers

From: Enrico Weigelt, metux IT consult
Date: Thu Jun 27 2019 - 10:59:08 EST


This is a little helper script for mailing patches out of a git
branch to the corresponding maintainers.

Essentially, it scans the touched files, asks get_maintainer.pl
for their maintainers and calls git-send-email for mailing out
the patches.

Syntax:

./scripts/git-send-patch <ref> [<optional git-send-email args>]

Examples:

./scripts/git-send-patch HEAD^
./scripts/git-send-patch linus/master --dry-run
