Hi All,
Sorry if I have missed out something I need to know before I
respond to this email. But the "trace" infrastructure (lib/trace.c)
already provides such a facility which more features such as per-cpu
buffer for faster transmission (it is a wrapper over "relay" which
sits on top of "debugfs").
The interfaces provided by "trace" are much simpler/functional than
setting up a "debugfs" interface manually (see
samples/trace/fork_trace.c) and the directory structure and control
files setup by "trace" are already familiar to the systemtap code.
Thanks,
K.Prasad
P.S.: "trace" is currently in -mm tree.
Thought it might be interesting to check this out--the patched 2.6.26-rc5 kernel built fine but panicked when I tried to boot it. So much for the easy way...

I know that you believe you understand what you think I said, but
I'm not sure you realize that what you heard is not what I meant.
