Subject: [PATCH 08/12] maple_tree: Replace mt_free_one() with kfree()
Date: Mon, 01 Sep 2025 13:08:58 +0200	[thread overview]
Message-ID: <20250901-maple-sheaves-v1-8-d6a1166b53f2@suse.cz> (raw)
In-Reply-To: <20250901-maple-sheaves-v1-0-d6a1166b53f2@suse.cz>

From: Pedro Falcato <pfalcato@suse.de>

kfree() is a little shorter and works with kmem_cache_alloc'd pointers
too. Also lets us remove one more helper.
