Subject: [RFC 29/32] eal: remove stale SMP barrier in rte_service
Date: Wed, 29 Jul 2026 10:54:22 -0700 [thread overview]
Message-ID: <20260729175715.165120-30-stephen@networkplumber.org> (raw)
In-Reply-To: <20260729175715.165120-1-stephen@networkplumber.org>
Leftover missed by the C11 atomics conversion of this file. The
barrier pairs with nothing: no store follows it, and the next use
of the lcore is synchronized by remote launch.
