Subject: [PATCH 1/3] sched: Relocate sched_smt_present definition to core.c
Date: Tue, 21 Oct 2025 16:55:42 +0200 [thread overview]
Message-ID: <20251021145706.61534-2-arighi@nvidia.com> (raw)
In-Reply-To: <20251021145706.61534-1-arighi@nvidia.com>
Multiple sched classes are using sched_smt_present, so move it from
fair.c to core.c, next to the helpers that update its state.
No functional changes.
