They're nondeterministic, and lead to ___might_sleep() splats in -rt.
OTOH, they're a lot less wasteful than an rtmutex per page.

Use disable_irq_nosync() instead of disable_irq() as this might be
called in atomic context with netpoll.

-While the use of synchronize_rcu_expedited() might make

+The forcing of an expedited grace period is an expensive and very
+RT-application unfriendly operation, as it forcibly preempts all running
+tasks on CPUs which are preventing the gp from expiring.
+
+By default, as a policy decision, disable the expediting of grace
+periods (after boot) on configurations which enable PREEMPT_RT_FULL.

+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.8/older/patches-4.8.11-rt7.tar.xz
+
+David reported a futex/rtmutex state corruption. It's caused by the
+following problem:
+
+CPU0 CPU1 CPU2
+
+l->owner=T1
+ rt_mutex_lock(l)
+ lock(l->wait_lock)
+ l->owner = T1 | HAS_WAITERS;
+ enqueue(T2)
+ boost()
+ unlock(l->wait_lock)
+ schedule()
+
+ rt_mutex_lock(l)
+ lock(l->wait_lock)
+ l->owner = T1 | HAS_WAITERS;
+ enqueue(T3)
+ boost()
+ unlock(l->wait_lock)
+ schedule()
+ signal(->T2) signal(->T3)
+ lock(l->wait_lock)
+ dequeue(T2)
+ deboost()
+ unlock(l->wait_lock)
+ lock(l->wait_lock)
+ dequeue(T3)
+ ===> wait list is now empty
+ deboost()
+ unlock(l->wait_lock)
+ lock(l->wait_lock)
+ fixup_rt_mutex_waiters()
+ if (wait_list_empty(l)) {
+ owner = l->owner & ~HAS_WAITERS;
+ l->owner = owner
+ ==> l->owner = T1
+ }
+
+ lock(l->wait_lock)
+rt_mutex_unlock(l) fixup_rt_mutex_waiters()
+ if (wait_list_empty(l)) {
+ owner = l->owner & ~HAS_WAITERS;
+cmpxchg(l->owner, T1, NULL)
+ ===> Success (l->owner = NULL)
+ l->owner = owner
+ ==> l->owner = T1
+ }
+
+That means the problem is caused by fixup_rt_mutex_waiters() which does the
+RMW to clear the waiters bit unconditionally when there are no waiters in
+the rtmutexes rbtree.
+
+This can be fatal: A concurrent unlock can release the rtmutex in the
+fastpath because the waiters bit is not set. If the cmpxchg() gets in the
+middle of the RMW operation then the previous owner, which just unlocked
+the rtmutex is set as the owner again when the write takes place after the
+successfull cmpxchg().
+
+The solution is rather trivial: Verify that the owner member of the rtmutex
+has the waiters bit set before clearing it. This does not require a
+cmpxchg() or other atomic operations because the waiters bit can only be
+set and cleared with the rtmutex wait_lock held. It's also safe against the
+fast path unlock attempt. The unlock attempt via cmpxchg() will either see
+the bit set and take the slowpath or see the bit cleared and release it
+atomically in the fastpath.
+
+It's remarkable that the test program provided by David triggers on ARM64
+and MIPS64 really quick, but it refuses to reproduce on x8664, while the
+problem exists there as well. That refusal might explain that this got not
+discovered earlier despite the bug existing from day one of the rtmutex
+implementation more than 10 years ago.
+
+Thanks to David for meticulously instrumenting the code and providing the
+information which allowed to decode this subtle problem.
