dtrace discuss - Apr 2007 - Tracing with ustack?

Hi,

ustack as I understand traces a maximum of depth stack frames from the user
process stack associated with the current thread.

I am currently tracing the user-level locks with plockstat.
I want to know for the every lock, the trace of the function calls that finally
lead to acquisition of the lock. So I am using the arg0 for printing the address
of the lock and ustack with a big number as a parameter so that it shows me the
list of all the function calls.

Is this a reasonable method?

Thanks,
Neelam

That sounds perfect.
