Subject: [PATCH 14/14] sched: Allow enabling proxy exec with sched_ext
Date: Sat, 25 Jul 2026 18:04:20 +0200 [thread overview]
Message-ID: <20260725160513.57477-15-arighi@nvidia.com> (raw)
In-Reply-To: <20260725160513.57477-1-arighi@nvidia.com>
Now that sched_ext can handle proxy donors and BPF schedulers can opt in
to blocked-donor enqueueing with SCX_OPS_ENQ_BLOCKED, remove the
!SCHED_CLASS_EXT dependency from SCHED_PROXY_EXEC and allow both options
to be enabled together.
