Subject: [PATCH 3/5] radix tree test suite: Add new tag check
Date: Tue, 13 Dec 2016 14:21:30 -0800	[thread overview]
Message-ID: <1481667692-14500-4-git-send-email-mawilcox@linuxonhyperv.com> (raw)
In-Reply-To: <1481667692-14500-1-git-send-email-mawilcox@linuxonhyperv.com>

From: Matthew Wilcox <mawilcox@microsoft.com>

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.
