Subject: [PATCH 00/48] RCU changes for v6.10
Date: Tue, 7 May 2024 11:34:42 +0200 [thread overview]
Message-ID: <20240507093530.3043-1-urezki@gmail.com> (raw)
This is for 6.10 kernel:
fixes: Fix a lockdep complain for lazy-preemptible kernel,
remove redundant BH disable for TINY_RCU, remove redundant READ_ONCE()
in tree.c, fix false positives KCSAN splat and fix buffer overflow in
the print_cpu_stall_info().
misc: Misc updates related to bpf, tracing and update the
MAINTAINERS file.
rcu-sync-normal-improve: An improvement of a normal
synchronize_rcu() call in terms of latency. It maintains a separate
track for sync. users only. This approach bypasses per-cpu nocb-lists
thus sync-users do not depend on nocb-list length and how fast regular
callbacks are processed.
rcu-tasks: RCU tasks, switch tasks RCU grace periods to
sleep at TASK_IDLE priority, fix some comments, add some diagnostic
warning to the exit_tasks_rcu_start() and fix a buffer overflow in
the show_rcu_tasks_trace_gp_kthread().
rcutorture: Increase memory to guest OS, fix a Tasks
Rude RCU testing, some updates for TREE09, dump mode information
to debug GP kthread state, remove redundant READ_ONCE(), fix some
comments about RCU_TORTURE_PIPE_LEN and pipe_count, remove some
redundant pointer initialization, fix a hung splat task by when
the rcutorture tests start to exit, fix invalid context warning,
add '--do-kvfree' parameter to torture test and use slow register
unregister callbacks only for rcutype test.
