I ask because the generic sched_clock() code is not NMI safe today. We were planning on making it NMI safe by doing something similar to what was done for ktime_get_mono_fast_ns() but we haven't gotten around to it. Mostly because no architecture that uses generic sched_clock() has support for NMIs right now. -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project
