From c3082a674f46fe49383b157882c41dfabaa37113 Mon Sep 17 00:00:00 2001 From: Amit Kucheria Date: Thu, 11 Jul 2019 19:51:25 +0530 Subject: PM: QoS: Get rid of unused flags The network_latency and network_throughput flags for PM-QoS have not found much use in drivers or in userspace since they were introduced. Commit 4a733ef1bea7 ("mac80211: remove PM-QoS listener") removed the only user PM_QOS_NETWORK_LATENCY in the kernel a while ago and there don't seem to be any userspace tools using the character device files either. PM_QOS_MEMORY_BANDWIDTH was never even added to the trace events. Remove all the flags except cpu_dma_latency. Signed-off-by: Amit Kucheria Acked-by: Pavel Machek Signed-off-by: Rafael J.
