Basic infrastructure for host - guest timestamp synchronization and a
POC implementation of PTP-like algorithm.
Tzvetomir Stoyanov (7):
trace-cmd: Implement new lib API: tracecmd_local_events_system()
trace-cmd: Add support for negative time offsets in trace.dat file
trace-cmd: Add implementations of htonll() and ntohll()
trace-cmd: Add new library APIs for ftrace instances.
trace-cmd: Find and store pids of tasks, which run virtual CPUs of
given VM
trace-cmd: Implement new API tracecmd_add_option_v()
trace-cmd: Implement new option in trace.dat file:
TRACECMD_OPTION_TIME_SHIFT
