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 Link: http://lkml.kernel.org/r/20160825152110.25663-3-dsafonov@virtuozzo.com Acked-by: Srikar Dronamraju <srikar@linux.vnet.ibm.com> Acked-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Dmitry Safonov <dsafonov@virtuozzo.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
