Review comment:
But from https://man7.org/linux/man-pages/man7/sched.7.html:
A SCHED_RR thread that has been preempted by a higher priority thread and
subsequently resumes execution as a running thread will complete the unexpired
portion of its round-robin time quantum.
At least, Linux kernel doesn't reset the time slice after suspend/resume
cycle.
