These classes track kernel calls.
_NTO_TRACE_KERCALL is a pseudo-class that comprises all these classes.
The traceprinter labels for these classes are KER_CALL, KER_EXIT, and INT_CALL, followed by an uppercase version of the kernel call; the IDE labels consist of the kernel call, followed by Enter, Exit, or INT.
Most of the events in these classes correspond in a fairly obvious way to the kernel calls; some correspond to internal functions:
