Hi Waiman,
For the first time in months I just turned of spinlock debugging on
my performance test machine and I just got an unpleasant surprise on
my standard inode allocation and reclaim test. I've described this
test to you before, because it's found regressions in your previous

perf_event_read() does two things:

- compute the total count of the event and its children
Not all callers need both. perf_event_reset() for instance needs the
first piece but doesn't need the second. Similarly, when we

Turn the cpu_chill() into a sched_yield() which is only used by those calling
spin_try_or_boost_lock(), as it will allow the owner of the lock, which had its
priority boosted (if needed), to run even with SCHED_FIFO tasks.
As there are still locations that use
From: "Steven Rostedt (Red Hat)"
In mainline Linux, there are cases where locks need to be taken in reverse
order. In non PREEMPT_RT code, spinlocks can not be preempted, thus if one
needs to take locks in reverse order, if it can't get the second lock, it
simply needs to release the first lock
(Frozen shark deflectors on)
Currently the solution to prevent the trylock livelock (described below)
is to change cpu_relax() to cpu_chill() that is simply a msleep(1) that
hopes that the owner of the lock runs and releases the lock and nobody
else takes that lock by the time the task wakes up
From: "Steven Rostedt (Red Hat)"
When trying to take locks in reverse order, it is possible that on
PREEMPT_RT that the running task could have preempted the owner and never
let it run, creating a live lock. This is because spinlocks in PREEMPT_RT
can be preempted.
Currently, this is solved by

Since evt structure is embedded in per-CPU mevt structure it's
definitely faster to use container_of() to get access to mevt
if we have evt (for example as incoming function argument) instead
of more expensive approach with this_cpu_ptr(_mct_tick).
this_cpu_ptr() on per-CPU mevt structure leads to

The function device_get_mac_address is trying different property names

addr (which contain the buffer pass by the caller) will be re-used. This
