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
