---------------------------------

             Summary: Refactor Subprocess logic in linux/perf.cpp to use common 
subroutine
                 Key: MESOS-3185
                 URL: https://issues.apache.org/jira/browse/MESOS-3185
             Project: Mesos
          Issue Type: Bug
          Components: slave
            Reporter: Paul Brett
            Assignee: Paul Brett


MESOS-2834 will enhance the perf isolator to support the different output 
formats provided by difference kernel versions.  In order to achieve this, it 
requires to execute the "perf --version" command. 

We should decompose the existing Subcommand processing in perf so that we can 
share the implementation between the multiple uses of perf.
