Re: kernel read fault using task_state()
I've pulled the pid2task() function from the source on the web:
http://sources.redhat.com/git/gitweb.cgi?p=systemtap.git;a=blob;f=tapset/task.stp;h=8776a0147220cb5ffc087cb949479e2ac207af0a;hb=HEAD
just as you advised.
and simply included the function into my systemtap-file.
it requires guru mode to run, but now I can translate my pid to a task number!
thank you!
