lsof为什么抱怨tracefs?
每次执行都会lsof发出有关TraceFS的警告: $ lsof any-file lsof: WARNING: can't stat() tracefs file system /sys/kernel/debug/tracing Output information may be incomplete. $ mount | grep trace tracefs on /sys/kernel/debug/tracing type tracefs (rw,relatime) (这是在Ubuntu 15.10上,已完全更新) 在正常运行期间安装TraceFS是否正常? 如果是这样,我如何告诉我lsof跳过它?
