    perf tools: Remove the '--(null)' long_name for --list-opts · 3ef1e65c
    Yunlong Song 提交于
    If the long_name of a 'struct option' is defined as NULL, --list-opts
    will incorrectly print '--(null)' in its output. As a result, '--(null)'
    will finally appear in the case of bash completion, e.g. 'perf record
    --'.
    
    Example:
    
    Before this patch:
    
     $ perf record --list-opts
    
     --event --filter --pid --tid --realtime --no-buffering --raw-samples
     --all-cpus --cpu --count --output --no-inherit --freq --mmap-pages
     --group --(null) --call-graph --verbose --quiet --stat --data
     --timestamp --period --no-samples --no-buildid-cache --no-buildid
     --cgroup --delay --uid --branch-any --branch-filter --weight
     --transaction --per-thread --intr-regs
    
    After this patch:
    
     $ perf record --list-opts
    
     --event --filter --pid --tid --realtime --no-buffering --raw-samples
     --all-cpus --cpu --count --output --no-inherit --freq --mmap-pages
     --group --call-graph --verbose --quiet --stat --data --timestamp
     --period --no-samples --no-buildid-cache --no-buildid --cgroup --delay
     --uid --branch-any --branch-filter --weight --transaction --per-thread
     --intr-regs
