We already have pid(), tid() and execname() in tapset/context.stp. I'm
wondering if somebody has written a tapset to get the command line of
the (current) task as well. Looking at proc_pid_cmdline in
fs/proc/base.c, I understand this information is in the user memory
tracked from the mm struct of the task (instead of the task struct
itself), so there is much more indirection to get it than pid, tid and
execname.
Thanks,
Yi Feng

Yes, I believe I have, but it's on a different system so will post later
unless someone else does.

Sorry, I have been on vacation. Now I look at my scipt I realise it uses
execname(), which is standard. It doesn't attempt to extract the full
command line.
