Subject: ftrace question

Hi, I apologize for the wide audience but I did not get response.
How to see the args passed to for example 
trace_ocfs2_dentry_attach_loc() using /sys/kernel/debug/tracing. I can 
only see function names and parent fn

               ls-4530  [000] .... 10532818.195802:
ocfs2_dentry_attach_lock <-ocfs2_lookup

It seems as though a separate formatter is used to print these
when traced with raw options or something like that.

Thanks
-Tariq Saeed
