Bug Description
This issue was only spotted on node Baltar (P9)
This is caused by the return value in:
$ cat /sys/devices/
0,8
The test was trying to use do arithmetic operation with it, but didn't expect to get a return value with a comma in it.
<<<test_start>>>
tag=cpuset_
cmdline=" cpuset_
contacts=""
analysis=exit
<<<test_output>>>
incrementing stop
/opt/ltp/
<<<execution_
initiation_
duration=0 termination_
cutime=0 cstime=0
<<<test_end>>>
Not sure if this is a test case issue, or if we should see a comma in /sys/devices/
