From d62df57370a5215fbf1b088d2ee51fa5d69bd0c3 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 10 Jan 2018 13:10:49 -0800 Subject: rcu: Remove obsolete force-quiescent-state statistics for debugfs The debugfs interface displayed statistics on RCU-pending checks but this interface has since been removed. This commit therefore removes the no-longer-used rcu_state structure's ->n_force_qs_lh and ->n_force_qs_ngp fields along with their updates. (Though the ->n_force_qs_ngp field was actually not used at all, embarrassingly enough.) If this information proves necessary in the future, the corresponding event traces will be added.
