Subject: [patch 01/25] debugobjects: Delete a piece of redundant code
Date: Mon, 7 Oct 2024 18:49:52 +0200 (CEST) [thread overview]
Message-ID: <20241007164913.009849239@linutronix.de> (raw)
In-Reply-To: 20241007163507.647617031@linutronix.de
From: Zhen Lei <thunder.leizhen@huawei.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.
