what's the meaning for args?
- local hackbench_path
- [ -f /lkp/benchmarks/hackbench-git/hackbench/hackbench ] && hackbench_path=/lkp/benchmarks/hackbench-git/hackbench/hackbench
too long line?
perhaps you like this:
[ -f /lkp/benchmarks/hackbench-git/hackbench/hackbench ] && { hackbench_path=/lkp/benchmarks/hackbench-git/hackbench/hackbench }
Thanks, Liushaofei
