From 4f3755d1ae3cd856a5c7da3dea12cced8dc51fbf Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Fri, 20 May 2016 17:02:14 -0700 Subject: radix tree test suite: start adding multiorder tests Test suite infrastructure for working with multiorder entries. The test itself is pretty basic: Add an entry, check that all expected indices return that entry and that indices around that entry don't return an entry. Then delete the entry and check no index returns that entry. Tests a few edge conditions including the multiorder entry at index 0 and at a higher index. Also tests deleting through an alias as well as through the canonical index.
