From 2e2e7ec1ef567ac0a4ad8294ada15836661e6589 Mon Sep 17 00:00:00 2001 From: Brad King Date: Mon, 27 Jan 2014 09:45:07 -0500 Subject: [PATCH] read-cache.c: refactor --ignore-missing implementation Move lstat ENOENT handling from refresh_index to refresh_cache_ent and activate it with a new CE_MATCH_IGNORE_MISSING option. This will allow other call paths into refresh_cache_ent to use the feature.
