Subject: [dpdk-dev] [PATCH v3 1/2] service: fix wrong lcore indices
Date: Tue, 7 Jul 2020 11:45:24 +0100
Message-ID: <1594118726-8421-1-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1593873347-13686-1-git-send-email-arybchenko@solarflare.com>

From: Igor Romanov <igor.romanov@oktetlabs.ru>

The service core list is populated, but not used. Incorrect
lcore states are examined for a service.

Use the populated list to iterate over service cores.

Fixes: e30dd31847d2 ("service: add mechanism for quiescing")
