Update git submodules
* Update docs/submodules/vswitchperf from branch 'master' - Merge "sysmetrics/pidstat: monitor all threads" - sysmetrics/pidstat: monitor all threads Since sysstat commit 52977c479d3d ("Introduce new SP_VALUE_100() macro and use it in pidstat"), pidstat can return a wrong CPU usage for all monitored PIDs. For example, if a process like ovs-vswitchd uses 2 threads, the CPU usage of each thread (TID) is equal to 100%, so the CPU usage of the main process (PID) must be equal at least to 200%. However, with this sysstat commit, the CPU usage is restricted to 100%. It is not possible to change this behavior. Now, pidstat is started in order to monitor all threads created by a process. As the output header has changed, readapt the existing code. In order to fix this issue, only the CPU usage is accumulated with all threads. For all other measures, main process should report correct values. JIRA: VSPERF-569 Change-Id: I98aa94f545d04f4de1b994c420fb5756c6f2a387 Signed-off-by: Julien Meunier <julien.meunier@6wind.com>
