From d9d7096662122f6b82ad6e4c08397b75906da78d Mon Sep 17 00:00:00 2001 From: Thomas Gummerer Date: Wed, 14 Sep 2016 22:07:46 +0100 Subject: read-cache: introduce chmod_index_entry As there are chmod options for both add and update-index, introduce a new chmod_index_entry function to do the work. Use it in update-index, while it will be used in add in the next patch.
