Subject: [PATCH 0/1] Fix deadlock problem and make performance better
Date: Fri, 30 Aug 2019 04:35:10 -0400 [thread overview]
Message-ID: <1567154111-23315-1-git-send-email-yanjun.zhu@oracle.com> (raw)
When running with about 1Gbit/ses for very long time, running ifconfig
and netstat causes dead lock. These symptoms are similar to the
commit 5f6b4e14cada ("net: dsa: User per-cpu 64-bit statistics"). After
replacing network devices statistics with per-cpu 64-bit statistics,
the dead locks disappear even after very long time running with 1Gbit/sec.
