Subject: [PATCH V3 1/8] sched: Remove unused TASK_SIZE_OF
Date: Tue, 28 Dec 2021 14:47:22 +0800 [thread overview]
Message-ID: <20211228064730.2882351-2-guoren@kernel.org> (raw)
In-Reply-To: <20211228064730.2882351-1-guoren@kernel.org>
From: Guo Ren <guoren@linux•alibaba.com>
This macro isn't used in Linux, now. Delete in include/linux/sched.h
and arch's include/asm. This would confuse people who are
implementing the COMPAT feature for architecture.
Here is the comment by Arnd:
Looking through the git history, I see commit a06db751c321 ("pagemap:
check permissions and capabilities at open time") removing the last
user.
