From 76efc1c770968d6c786e5340029f8005ed29b2a5 Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Thu, 10 Dec 2020 18:56:44 +0800 Subject: blk-iocost: Add iocg idle state tracepoint It will be helpful to trace the iocg's whole state, including active and idle state. And we can easily expand the original iocost_iocg_activate trace event to support a state trace class, including active and idle state tracing.
