Subject: [PATCH 17/17] sched: Allow enabling proxy exec with sched_ext
Date: Sun, 16 Aug 2026 19:35:15 +0200	[thread overview]
Message-ID: <20260816173732.17162-18-arighi@nvidia.com> (raw)
In-Reply-To: <20260816173732.17162-1-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.

Acked-by: John Stultz <jstultz@google.com>
