Is this irq_work frame work designed to run works from ARMPMU irq handlers? If there are no of drivers using the IRQ WORK frame work, we may see that ARMPMU irq handler taking long time, right? -Thanks, Prasad -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, Linux Foundation Collaborative Project
