Subject: [PATCH tip/core/rcu 0/12] Miscellaneous fixes for v5.4
Date: Thu, 1 Aug 2019 15:37:08 -0700 [thread overview]
Message-ID: <20190801223708.GA14862@linux.ibm.com> (raw)
Hello!
This series contains miscellaneous fixes:
1. Make lockdep's print_lock() address visible.
2. Fix tick_broadcast_offline() lockdep complaint.
3. Restore barrier() to rcu_read_lock() and rcu_read_unlock().
4. Add kernel parameter to dump trace after RCU CPU stall warning.
5. Add destroy_work_on_stack() to match INIT_WORK_ONSTACK().
6. Avoid srcutorture security-based pointer obfuscation.
7. Change return type of rcu_spawn_one_boost_kthread(), courtesy of
Byungchul Park.
8. Add rcutree.kthread_prio pointer to stallwarn.txt.
9. Prevent late-arriving interrupts from disrupting offline, courtesy
of Peter Zijlstra.
10. Remove redundant "if" condition from rcu_gp_is_expedited().
11. Use common outgoing-CPU-notification code for arm.
12. Fix spelling mistake "greate"->"great", courtesy of Mukesh Ojha.
Thanx, Paul
