Message-ID: <20241007164913.009849239@linutronix.de> Date: Mon, 7 Oct 2024 18:49:52 +0200 (CEST) From: Thomas Gleixner <tglx@...utronix.de> To: LKML <linux-kernel@...r.kernel.org> Cc: Zhen Lei <thunder.leizhen@...wei.com>, Waiman Long <longman@...hat.com> Subject: [patch 01/25] debugobjects: Delete a piece of redundant code From: Zhen Lei <thunder.leizhen@...wei.com> The statically allocated objects are all located in obj_static_pool[], the whole memory of obj_static_pool[] will be reclaimed later. Therefore, there is no need to split the remaining statically nodes in list obj_pool into isolated ones, no one will use them anymore. Just write INIT_HLIST_HEAD(&obj_pool) is enough. Since hlist_move_list() directly discards the old list, even this can be omitted.
