It's useless. Before: [tracing]# echo 'p:test /a:0x0' >> uprobe_events [tracing]# echo 'p:test a:0x0' >> uprobe_events -bash: echo: write error: No such file or directory [tracing]# echo 'p:test 1:0x0' >> uprobe_events -bash: echo: write error: Invalid argument
After: [tracing]# echo 'p:test 1:0x0' >> uprobe_events -bash: echo: write error: No such file or directory
