Subject: [PATCH v3 3/3] kernel/fork.c: put set_max_threads()/task_struct_whitelist() in __init section
Date: Wed,  3 Jul 2024 00:51:51 +0000	[thread overview]
Message-ID: <20240703005151.28712-3-richard.weiyang@gmail.com> (raw)
In-Reply-To: <20240703005151.28712-1-richard.weiyang@gmail.com>

Function set_max_threads()/task_struct_whitelist() is only used by
fork_init() during bootup.

Let's add __init tag to them.
