From b87fc96476c4218de044cf77b4c6d10d49aee78a Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 20 May 2009 15:53:57 -0700 Subject: [PATCH] cache-tree.c::cache_tree_find(): simplify internal API Earlier cache_tree_find() needs to be called with a valid cache_tree, but repeated look-up may find an invalid or missing cache_tree in between. Help simplify the callers by returning NULL to mean "nothing appropriate found" when the input is NULL.
