retval
return value of the syscall
The process performing the syscall
The syscall_any.return probe point is designed to be a low overhead that monitors all the syscalls returns via a kernel tracepoint. Because of the breadth of syscalls it monitors it provides no information about the syscall arguments, argstr string representation of those arguments, or a string interpretation of the return value (retval).
This requires kernel 3.5+ and newer which have the kernel.trace(“sys_exit”) probe point.
