From: Linus Torvalds Date: Thu, 6 Mar 2008 20:26:14 +0000 (-0800) Subject: Make 'unpack_trees()' take the index to work on as an argument X-Git-Tag: v1.5.5-rc0~25^2~4 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=bc052d7f435f8f729127cc4790484865c1a974b9;p=git.git Make 'unpack_trees()' take the index to work on as an argument This is just a very mechanical conversion, and makes everybody set it to '&the_index' before calling, but at least it makes it more explicit where we work with the index. The next stage would be to split that index usage up into a 'source' and a 'destination' index, so that we can unpack into a different index than we started out from.
