[PATCH 02/20] perf tools: Compare JOBS to 0 after grep

[Arnaldo Carvalho de Melo]

From: David Ahern <david.ahern@xxxxxxxxxx>

If JOBS is not by user perf tries to autodetect the number by grepping
the number of CPUs from /proc/cpuinfo. 'grep -c' will always return an
integer so after this command JOBS should be compared to 0, not "".
