Subject: [PATCH tip/core/rcu 10/40] rcu: Make rcu_note_context_switch() do deferred NOCB wakeups
Date: Wed, 12 Apr 2017 10:39:55 -0700	[thread overview]
Message-ID: <1492018825-25634-10-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170412174003.GA23207@linux.vnet.ibm.com>

If a CONFIG_RCU_NOCB_CPUS kernel invokes call_rcu() with interrupts
disabled, wakeups must be deferred in order to avoid self-deadlock in the
cases where the disabled interrupts are due to scheduler locks being held.
In this case, a flag is set and is checked on entry to extended quiescent
states (usermode, idle), on exit from the RCU_SOFTIRQ handler, when the
CPU in question goes offline, on a subsequent invocation of call_rcu(),
and from rcu_all_qs().  However, a given CPU could avoid all of those
states for a considerable length of time.

This commit therefore allows an invocation of rcu_note_context_switch()
to do the wakeup.  It also makes the wakeup function clear the
deferred-wakeup flag.
