perf tools: Fix the bash completion for listing options of perf subcommand
The bash completion does not support listing options for 'perf
kvm|kmem|mem|lock|sched --<TAB>', where 'kvm|kmem|mem|lock|sched' are
all subcommands of perf.
Example:
Before this patch:
$ perf kvm --<TAB>
$
As shown above, the options of perf kvm does not come out.
After this patch:
$ perf kvm --<TAB>
--alloc --caller --input --line --raw-ip --sort
--verbose
As shown above, the options of perf kvm can come out now.
