All interrupts which must be non threaded are marked
IRQF_NO_THREAD. So it's safe to allow force threaded handlers.

When a runqueue is throttled we cannot disable the period timer
because that timer is the only way to undo the throttling.

The arm boot_lock is used by the secondary processor startup code. The locking
task is the idle thread, which has idle->sched_class == &idle_sched_class.

remove timer calls (!!!) from deep within the tracing infrastructure.
This was totally bogus code that can cause lockups and worse. Poll

Change from task_rq_lock() to raw_spin_lock(&rq->lock) to avoid a few
atomic ops. See comment on why it should be safe.

as changing the affinity is expensive to do at every lock encountered.

The ntp code for notify_cmos_timer() is called from a hard interrupt

The hwlat-detector needs a better clock than just ktime_get() as that
can induce its own latencies. The trace clock is perfect for it, but

+
+Since lapic timer handler only wakes up a simple waitqueue,
+it can be executed from hardirq context.
+
+Also handle the case where hrtimer_start_expires fails due to -ETIME,
+by injecting the interrupt to the guest immediately.
+
+Reduces average cyclictest latency by 3us.

+
+Initializing a new slab can introduce rather large latencies because most
+of the initialization runs always with interrupts disabled.
+
+There is no point in doing so. The newly allocated slab is not visible
+yet, so there is no reason to protect it against concurrent alloc/free.
+
+Move the expensive parts of the initialization into allocate_slab(), so
+for all allocations with GFP_WAIT set, interrupts are enabled.

+Subject: [PATCH 373/374] xfs: Disable percpu SB on PREEMPT_RT_FULL
+Origin: https://git.kernel.org/cgit/linux/kernel/git/rt/linux-stable-rt.git/commit?id=e002511348cd633a010535583bd9ba3e07cbd4d0
+
+Running a test on a large CPU count box with xfs, I hit a live lock
+with the following backtraces on several CPUs:
+
+ Call Trace:
+ [<ffffffff812c34f8>] __const_udelay+0x28/0x30
+ [<ffffffffa033ab9a>] xfs_icsb_lock_cntr+0x2a/0x40 [xfs]

+ [<ffffffff811b21ef>] do_last+0xb8f/0x1240
+ [<ffffffff811b39b2>] path_openat+0xc2/0x490
+
+Looking at the code I see it was stuck at:
+
+STATIC void
+xfs_icsb_lock_cntr(
+ xfs_icsb_cnts_t *icsbp)
+{
+ while (test_and_set_bit(XFS_ICSB_FLAG_LOCK, &icsbp->icsb_flags)) {
+ ndelay(1000);
+ }
+}
+
+In xfs_icsb_modify_counters() the code is fine. There's a
+preempt_disable() called when taking this bit spinlock and a
+preempt_enable() after it is released. The issue is that not all
+locations are protected by preempt_disable() when PREEMPT_RT is set.
+Namely the places that grab all CPU cntr locks.
+
+STATIC void
+xfs_icsb_lock_all_counters(
+ xfs_mount_t *mp)
+{
+ xfs_icsb_cnts_t *cntp;
+ int i;
+
+ for_each_online_cpu(i) {
+ cntp = (xfs_icsb_cnts_t *)per_cpu_ptr(mp->m_sb_cnts, i);
+ xfs_icsb_lock_cntr(cntp);
+ }
+}
+
+STATIC void
+xfs_icsb_disable_counter()
+{
+ [...]
+ xfs_icsb_lock_all_counters(mp);
+ [...]
+ xfs_icsb_unlock_all_counters(mp);
+}
+
+STATIC void
+xfs_icsb_balance_counter_locked()
+{
+ [...]
+ xfs_icsb_disable_counter();
+ [...]
+}
+
+STATIC void
+xfs_icsb_balance_counter(
+ xfs_mount_t *mp,
+ xfs_sb_field_t fields,
+ int min_per_cpu)
+{
+ spin_lock(&mp->m_sb_lock);
+ xfs_icsb_balance_counter_locked(mp, fields, min_per_cpu);
+ spin_unlock(&mp->m_sb_lock);
+}
+
+Now, when PREEMPT_RT is not enabled, that spin_lock() disables
+preemption. But for PREEMPT_RT, it does not. Although with my test box I
+was not able to produce a task state of all tasks, but I'm assuming that
+some task called the xfs_icsb_lock_all_counters() and was preempted by
+an RT task and could not finish, causing all callers of that lock to
+block indefinitely.
+
+Dave Chinner has stated that the scalability of that code will probably
+be negated by PREEMPT_RT, and that it is probably best to just disable
+the code in question. Also, this code has been rewritten in newer kernels.
