JIRA: https://issues.redhat.com/browse/RHEL-79879 commit 0ac55d095d375e84fcdac5e51011613734e57854 Author: Paul E. McKenney <paulmck@kernel.org> Date: Wed May 8 21:43:56 2024 -0700 This commit adds a tools/rcu/rcu-updaters.sh script that uses bpftrace to print a histogram of the RCU update-side primitives invoked during the specified time interval, or until manually terminated if no interval is specified. Sample output on an idle laptop: @counts[poll_state_synchronize_rcu]: 6 @counts[synchronize_srcu]: 13 @counts[call_rcu_tasks_trace]: 25 @counts[synchronize_rcu]: 54 @counts[kvfree_call_rcu]: 428 @counts[call_rcu]: 2134 Note that when run on a kernel missing one or more of the symbols, this script will issue a diagnostic for each that is not found, but continue normally for the rest of the functions.
