Sorry about that, I'm spoiled with a distro that makes debuginfo
really easy to find & install. :-) I should have listed this variant
of the script instead. It doesn't need debuginfo (because stap
developers have coded up a considerable heuristic database for
syscalls).
# stap -e '
probe nd_syscall.{adjtimex,clock_adjtime,clock_settime}
{ println(tid(), " ", ppfunc()," ",argstr) }
probe nd_syscall.{adjtimex,clock_adjtime,clock_settime}.return
{ println(tid(), " ", ppfunc()," ",retstr) }
'
25234 sys_adjtimex {ADJ_OFFSET|ADJ_MAXERROR|ADJ_ESTERROR|ADJ_STATUS|ADJ_TIMECONST, constant=3, esterror=16, freq=0, maxerror=16, offset=0, precision=0, status=1, tick=0, tolerance=0}
25234 sys_adjtimex 0 (TIME_OK)
