From 55850945e872531644f31fefd217d61dd15dcab8 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 29 Apr 2012 22:53:32 +0200 Subject: PM / Sleep: Add "prevent autosleep time" statistics to wakeup sources Android uses one wakelock statistics that is only necessary for opportunistic sleep. Namely, the prevent_suspend_time field accumulates the total time the given wakelock has been locked while "automatic suspend" was enabled. Add an analogous field, prevent_sleep_time, to wakeup sources and make it behave in a similar way. Signed-off-by: Rafael J.
