02:30:49 2025 -0700 lockdep: Speed up lockdep_unregister_key() with expedited RCU synchronization lockdep_unregister_key() is called from critical code paths, including sections where rtnl_lock() is held. For example, when replacing a qdisc in a network device, network egress traffic is disabled while __qdisc_destroy() is called for every network queue. If lockdep is enabled, __qdisc_destroy() calls lockdep_unregister_key(), which gets blocked waiting for synchronize_rcu() to complete. For example, a simple tc command to replace a qdisc could take 13 seconds: # time /usr/sbin/tc qdisc replace dev eth0 root handle 0x1: mq real 0m13.195s user 0m0.001s sys 0m2.746s During this time, network egress is completely frozen while waiting for RCU synchronization. Use synchronize_rcu_expedited() instead to minimize the impact on critical operations like network connectivity changes. This improves 10x the function call to tc, when replacing the qdisc for a network card. # time /usr/sbin/tc qdisc replace dev eth0 root handle 0x1: mq real 0m1.789s user 0m0.000s sys 0m1.613s [boqun: Fixed the comment and add more information for the temporary workaround, and add TODO information for hazptr] Reported-by: Erik Lundgren Signed-off-by: Breno Leitao Reviewed-by: Paul E.
