Subject: [PATCH 01/41] maple_tree: Be more cautious about dead nodes
Date: Mon, 9 Jan 2023 12:52:56 -0800 [thread overview]
Message-ID: <20230109205336.3665937-2-surenb@google.com> (raw)
In-Reply-To: <20230109205336.3665937-1-surenb@google.com>
From: Liam Howlett <Liam.Howlett@oracle.com>
ma_pivots() and ma_data_end() may be called with a dead node. Ensure to
that the node isn't dead before using the returned values.
This is necessary for RCU mode of the maple tree.
Fixes: 54a611b60590 ("Maple Tree: add new data structure")
