From 20a16eb33eee99fd3eab00c72f012b98d4eeee76 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 10 Mar 2008 23:51:13 -0700 Subject: unpack_trees(): fix diff-index regression. When skip_unmerged option is not given, unpack_trees() should not just skip unmerged cache entries but keep them in the result for the caller to sort them out. For callers other than diff-index, the incoming index should never be unmerged, but diff-index is a special case caller.
