From bec06785fe2c866ccf39cafa18935d88d77d559a Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 10 Jan 2018 12:16:42 -0800 Subject: rcu: Remove obsolete boost statistics for debugfs The debugfs interface displayed statistics on RCU priority boosting, but this interface has since been removed. This commit therefore removes the no-longer-used rcu_data structure's ->n_tasks_boosted, ->n_exp_boosts, and ->n_exp_boosts and their updates. If this information proves necessary in the future, the corresponding event traces will be added. Signed-off-by: Paul E.
