This patchset adds a couple of needed "notrace" declarations and one
of two needed CPU-hotplug rcutree plugins. This applies on top of
current tip/core/rcu, but is a temporary fix. The problem with it is
that it is not bisectable when using ftrace.
This will be replaced with a later rework of the tip/core/rcu patch
stack.

So notrace is needed to make sure we do not trace such function call.

Unless someone has a better idea, I will send in a patch that adds "notrace" to every RCU API member used by any file in the kernel that has "trace" in its name (excluding ptrace.c and rcutree_trace.c, of course).

I think the callers should be fixed rather than RCU. Tracepoints have been designed to use the _notrace variant on the instrumentation site. The core of tracepoint management use call_rcu_sched(), which can be traced without any problem. I have not followed the late tracing development as closely though, so errors might have crept in.

Or I might have inadvertently broken something in a non-obvious (to me, anyway) manner. So, would you be willing to look at commit bc33f24bd in the -tip tree and see if there is anything I broke other than the now-fixed rcu_read_lock_sched_notrace() and rcu_read_unlock_sched_notrace()? And for that matter, whether my alleged fix for these two API members really does fix the problem (-tip commit 7c614d6461)? The -tip tree is at: git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git And these patches are on the tip/core/rcu branch.

I don't think this is correct, and this might be causing your problem. rcu_read_acquire/release are calling lock_acquire/release, those should be removed. __acquire() simply seems to be defined to a gcc "context" attribute, probably for the sparse checker. I think it should be safe to leave them there.

Thanx, Paul ------------------------------------------------------------------------ Remove lockdep annotations from RCU's _notrace() API members. The lockdep annotations rcu_read_acquire() and rcu_read_release() might lead to infinite looping if called from lockdep. So this patch removes them.
