If a process is executing a system call, and an interrupt is invoked, the process blocks. Now since interrupt handlers cannot block, the time for which the IH runs is taken out of the process's time-slice ( Is this right ?). What if the IH takes up all of the process's time-slice, does the process gets knocked off the current list and thrown into the expired list or is there something more to it? thanks for your time - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
