Hi Valdis, Understood.
I though preemptible only means that a process can only be preempted (not moved to another core) under following situations:
1) An interrupt happens (In case of timer, it could put the process back in queue if its time slice expired).
Actually, in case of any interrupt, be it timer or I/O or NMI or whatever.
So, essentially a scheduler can kick in while returning from ANY sort of interrupt (and not just timer interrupt), right? Thanks, Rajat
