Subject: [PATCH 6.6 11/28] maple_tree: use cached node end in mas_destroy()
Date: Thu, 24 Oct 2024 21:19:52 +0800	[thread overview]
Message-ID: <20241024132009.2267260-12-yukuai1@huaweicloud.com> (raw)
In-Reply-To: <20241024132009.2267260-1-yukuai1@huaweicloud.com>

From: "Liam R. Howlett" <Liam.Howlett@oracle.com>

commit 1f41ef12abf8538b3d82cdae14c06aa171cb71ce upstream.

The node end is set during the walk, so use the resulting end instead of
re-fetching it.
