From: Joe Perches <joe@...ches.com>
To: linux-kernel@...r.kernel.org
Subject: [PATCH 3/8] scripts/get_maintainer.pl: Update --interactive UI, improve hg runtime
o Add option --git-blame-signatures default:on to search each
commit used by the current file for signatures
o Use consistent style in VCS_cmds_(git|hg)
o Add more options to be controlled at the --interactive prompt
o Speed up hg commit searching runtime by issuing a single
hg command to search all modified commits instead of running
multiple hg commands with a single commit each.
Update to 0.26 beta3
