Subject[PATCH v2] scripts: helper for mailing patches from git to the maintainers
Date
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
