ksym_tracer: Fix the output of stat tracing
- make ksym_tracer_stat_start() return head->first instead of &head->first - make the output properly aligned Before: Access type Symbol Counter NA <NA> 0 RW pid_max 0 After: Access Type Symbol Counter ----------- ------ ------- RW pid_max 0 Signed-off-by: Li Zefan <lizf@cn.fujitsu.com> Acked-by: Frederic Weisbecker <fweisbec@gmail.com> Cc: "K.Prasad" <prasad@linux.vnet.ibm.com> Cc: Alan Stern <stern@rowland.harvard.edu> Cc: Steven Rostedt <rostedt@goodmis.org> LKML-Reference: <4A52E346.5050608@cn.fujitsu.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
