Subject: [PATCH 2/2] maple_tree: remove sanity check from mas_wr_slot_store()
Date: Wed, 16 Oct 2024 00:22:21 +0000	[thread overview]
Message-ID: <20241016002221.32428-3-richard.weiyang@gmail.com> (raw)
In-Reply-To: <20241016002221.32428-1-richard.weiyang@gmail.com>

After commit 5d659bbb52a2 ("maple_tree: introduce mas_wr_store_type()"),
the check here is redundant.

Let's remove it.
