Subject: [PATCH v2 08/15] merge-recursive: remove ren[12]_other fields from rename_conflict_info
Date: Fri, 29 Mar 2019 17:33:29 -0700	[thread overview]
Message-ID: <20190330003336.21940-9-newren@gmail.com> (raw)
In-Reply-To: <20190330003336.21940-1-newren@gmail.com>

The ren1_other and ren2_other fields were synthesized from information
in ren1->src_entry and ren2->src_entry.  Since we already have the
necessary information in ren1 and ren2, just use those.
