Browse Source

  [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
