Subject: [dpdk-stable] [PATCH v2 3/4] test/lpm: remove error checking in rcu qsbr perf
Date: Mon,  2 Nov 2020 17:52:02 -0600
Message-ID: <20201102235203.6342-4-dharmik.thakkar@arm.com> (raw)
In-Reply-To: <20201102235203.6342-1-dharmik.thakkar@arm.com>

Remove redundant error checking for reader threads
since they never return error.

Fixes: eff30b59cc2e ("test/lpm: add RCU performance tests")
Cc: honnappa.nagarahalli@arm.com
Cc: stable@dpdk.org
