From 02fde323b9aaebb4a21e7c0e04759470b6c07594 Mon Sep 17 00:00:00 2001 From: Yunlong Song Date: Wed, 18 Mar 2015 21:35:46 +0800 Subject: [PATCH] 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 --', where 'kvm|kmem|mem|lock|sched' are all subcommands of perf. Example: Before this patch: $ perf kvm -- $ As shown above, the options of perf kvm does not come out. After this patch: $ perf kvm -- --alloc --caller --input --line --raw-ip --sort --verbose As shown above, the options of perf kvm can come out now.
