From a706e8f6fc19c5f94108fd2253993b7e4e9b34d8 Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Wed, 14 Feb 2018 10:51:49 -0800 Subject: merge-recursive: move the get_renames() function Move this function so it can re-use some others (without either moving all of them or adding an annoying split between function declarations and definitions). Cheat slightly by adding a blank line for readability, and in order to silence checkpatch.pl.
