Subject: [PATCH v5 2/4] x86/smpboot: remove redundant CONFIG_SCHED_SMT
Date: Thu, 10 Jul 2025 18:57:08 +0800 [thread overview]
Message-ID: <20250710105715.66594-3-me@linux.beauty> (raw)
In-Reply-To: <20250710105715.66594-1-me@linux.beauty>
From: Li Chen <chenl311@chinatelecom.cn>
CONFIG_SCHED_SMT is default y if SMP is enabled,
so let's simply drop CONFIG_SCHED_SMT.
