Subject: [PATCH v2 1/9] read-cache.c: move index_has_changes() from merge.c
Date: Sat, 30 Jun 2018 18:24:55 -0700 [thread overview]
Message-ID: <20180701012503.14382-2-newren@gmail.com> (raw)
In-Reply-To: <20180701012503.14382-1-newren@gmail.com>
Since index_has_change() is an index-related function, move it to
read-cache.c, only modifying it to avoid uses of the active_cache and
active_nr macros.
