Subject: [PATCH 21/34] maple_tree: mas_start() reset depth on dead node
Date: Tue, 25 Apr 2023 10:09:42 -0400 [thread overview]
Message-ID: <20230425140955.3834476-22-Liam.Howlett@oracle.com> (raw)
In-Reply-To: <20230425140955.3834476-1-Liam.Howlett@oracle.com>
When a dead node is detected, the depth has already been set to 1 so
reset it to 0.
