Subject: SUNRPC: Limit the rpciod workqueue concurrency
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9b96ce71974127af0304514d310abe596426c112;p=openwrt%2Fstaging%2Fblogic.git

SUNRPC: Limit the rpciod workqueue concurrency

We shouldn't need more than 1 worker thread per cpu, since rpciod
is designed to run without sleeping in most cases.
