Subject: [dpdk-dev] [PATCH v2 1/2] eal: fix potential incorrect pinning for ctrl threads
Date: Thu, 14 Feb 2019 14:30:41 +0100 [thread overview]
Message-ID: <1550151042-9764-1-git-send-email-david.marchand@redhat.com> (raw)
In-Reply-To: <1550074412-31285-1-git-send-email-david.marchand@redhat.com>
pthread_setaffinity_np returns a >0 value on error.
We could end up letting the ctrl threads on the current process cpu
affinity.
Fixes: d651ee4919cd ("eal: set affinity for control threads")
