From 6af926e8bcab15b42faeee9f2fe1c69b5fea1b15 Mon Sep 17 00:00:00 2001 From: Ronnie Sahlberg Date: Fri, 20 Jun 2014 07:42:47 -0700 Subject: lockfile.c: add a new public function unable_to_lock_message Introducing a new unable_to_lock_message helper, which has nicer semantics than unable_to_lock_error and cleans up lockfile.c a little.
