I don't know the answer to your question and I don't have access to
AIX. Why not type man -k preemption on AIX to see if you get anything?
BTW, schedctl_* are library functions, not syscalls. Knowing this is important so that you know you can't run truss on an Oracle process expecting to see schedctl_* calls (like truss -t schedctl_init -p 12345). But I'm not sure what system call should be expected from truss? Maybe a flag in crash utility u -f or p -f command can tell us?
