Subject: vhost: suppress error if NUMA is not available
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d02f2092a31457b6477e7e995f9b0ca122d951bc;p=dpdk.git

vhost: suppress error if NUMA is not available

It's a common case that 'get_mempolicy' fails on systems
without NUMA support. No need to flag an error in log for
this situation.
