From 092bc0b225a9bdb6dca0959ddd6826afb6d40747 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox <mawilcox@microsoft.com> Date: Wed, 14 Dec 2016 15:09:34 -0800 Subject: [PATCH] radix tree test suite: add new tag check We have a check that setting a tag on a single entry at root succeeds, but we were missing a check that clearing a tag on that same entry also succeeds.
