There is no reason to do it twice: from commit b6f11df2
("trace: Call tracing_reset_online_cpus before tracer->init()")
resetting of per-CPU buffers done before tracer->init() call.

tracer->init() calls {irqs,preempt,preemptirqs}off_tracer_init() and it
calls __irqsoff_tracer_init(), which resets per-CPU ringbuffer second
time.
It's slowpath, but anyway.

If tracing contains data and the trace_pipe file is read with sendfile(),
then it can trigger a NULL pointer dereference and various BUG_ON within the
VM code.

There's a patch to fix this in the splice_to_pipe() code, but it's also a
good idea to not let that happen from trace_pipe either.

Joel Fernandes reported that the function tracing of preempt disabled
sections was not being reported when running either the preemptirqsoff or
preemptoff tracers. This was due to the fact that the function tracer
callback for those tracers checked if irqs were disabled before tracing. But
this fails when we want to trace preempt off locations as well.

Joel explained that he wanted to see funcitons where interrupts are enabled
but preemption was disabled. The expected output he wanted:

There's a comment saying that the irq disabled check is because there's a
possible race that tracing_cpu may be set when the function is executed. But
I don't remember that race. For now, I added a check for preemption being
enabled too to not record the function, as there would be no race if that
was the case. I need to re-investigate this, as I'm now thinking that the
tracing_cpu will always be correct. But no harm in keeping the check for
now, except for the slight performance hit.

Currently dynamic ftrace calls are updated any time
the ftrace_ops is un/registered. If we do  this update
only when it's needed, we save lot of time for perf
system wide ftrace function sampling/counting.

The reason is that for system wide sampling/counting,
perf creates event for each cpu in the system.

Each event then registers separate copy of ftrace_ops,
which ends up in FTRACE_UPDATE_CALLS updates. On servers
with many cpus that means serious stall (240 cpus server):

Counting:
  # time ./perf stat -e ftrace:function -a sleep 1

   Performance counter stats for 'system wide':

              370,663      ftrace:function

  real    2m31.429s
  user    0m0.213s
  sys     2m29.494s

There's no reason to do the FTRACE_UPDATE_CALLS update
for each event in perf case, because all the ftrace_ops
always share the same filter, so the updated calls are
always the same.

It's required that only first ftrace_ops registration
does the FTRACE_UPDATE_CALLS update (also sometimes
the second if the first one used the trampoline), but
the rest can be only cheaply linked into the ftrace_ops
list.

With unlocked kernfs_* functions, synchronize_sched() has to be called in
kernfs_rename which could be called in syscall path, but it is problematic.
So, print out cgroup ino instead of path name, which could be converted to
path name by userland.

Withouth CGROUP_WRITEBACK enabled, it just prints out root dir. But, root
dir ino vary from different filesystems, so printing out -1U to indicate
an invalid cgroup ino.

Add a new needs_rec flag for triggers that require unconditional
access to trace records in order to function.

Normally a trigger requires access to the contents of a trace record
only if it has a filter associated with it (since filters need the
contents of a record in order to make a filtering decision).  Some
types of triggers, such as 'hist' triggers, require access to trace
record contents independent of the presence of filters, so add a new
flag for those triggers.

Some trace events have conditions that check if the current CPU is online or
not before recording the tracepoint. That's because certain trace events are
in locations that can be called as the CPU is going offline and when RCU no
longer monitors it (like kfree and friends). The check was added because
trace events require RCU to be active.

This is a trace event infrastructure issue and not something that individual
trace events should worry about. The tracepoint.h code now has added a check
to see if the current CPU is considered online, and it only does the
tracepoint if it is. There's no more need for individual trace events to
also include this check. It is now redundant.

When I was updating the ftrace_stress test of ltp. I encountered
a strange phenomemon, excute following steps:

echo nop > /sys/kernel/debug/tracing/current_tracer
echo 0 > /sys/kernel/debug/tracing/options/funcgraph-cpu
bash: echo: write error: Invalid argument

check dmesg:
[ 1024.903855] nop_test_refuse flag set to 0: we refuse.Now cat trace_options to see the result

The reason is that the trace option test will randomly setup trace
option under tracing/options no matter what the current_tracer is.
but the set_tracer_option is always using the set_flag callback
from the current_tracer. This patch adds a pointer to tracer_flags
and make it point to the tracer it belongs to. When the option is
setup, the set_flag of the right tracer will be used no matter
what the the current_tracer is.

And the old dummy_tracer_flags is used for all the tracers which
doesn't have a tracer_flags, having issue to use it to save the
pointer of a tracer. So remove it and use dynamic dummy tracer_flags
for tracers needing a dummy tracer_flags, as a result, there are no
tracers sharing tracer_flags, so remove the check code.

And save the current tracer to trace_option_dentry seems not good as
it may waste mem space when mount the debug/trace fs more than one time.

Pull sound fixes from Takashi Iwai:
 "It's our tradition to get a high volume of fixes late at rc7: this
  time, X32 ABI breakage was found and this resulted in a high number
  LOCs.  The necessary changes to ALSA core codes were fairly
  straightforward, and more importantly, they are specific to X32, thus
  should be safe to apply.

  Other than that, rather a collection of small fixes:
   - Removal of the code that blocks too long at closing the OSS
     sequencer client (which was spotted by syzkaller, unsurprisingly)
   - Fixes races at HD-audio HDMI i915 audio binding
   - a few HDSP/HDPM zero-division fixes
   - Quirks for HD-audio and USB-audio as usual"

Pull libnvcimm fix from Dan Williams:
 "One straggling fix for NVDIMM support.

  The KVM/QEMU enabling for NVDIMMs has recently reached the point where
  it is able to accept some ACPI _DSM requests from a guest VM.  However
  they immediately found that the 4.5-rc kernel is unusable because the
  kernel's 'nfit' driver fails to load upon seeing a valid "not
  supported" response from the virtual BIOS for an address range scrub
  command.

  It is not mandatory that a platform implement address range scrubbing,
  so this fix from Vishal properly treats the 'not supported' response
  as 'skip scrubbing and continue loading the driver'"

Pull SCSI fixes from James Bottomley:
 "Two fairly simple fixes.

  One is a regression with ipr firmware loading caused by one of the
  trivial patches in the last merge window which failed to strip the \n
  from the file name string, so now the firmware loader no longer works
  leading to a lot of unhappy ipr users; fix by stripping the \n.

  The second is a memory leak within SCSI: the BLK_PREP_INVALID state
  was introduced a recent fix but we forgot to account for it correctly
  when freeing state, resulting in memory leakage.  Add the correct
  state freeing in scsi_prep_return()"

Pull libata fixes from Tejun Heo:
 "Assorted fixes for libata drivers.

   - Turns out HDIO_GET_32BIT ioctl was subtly broken all along.

   - Recent update to ahci external port handling was incorrectly
     marking hotpluggable ports as external making userland handle
     devices connected to those ports incorrectly.

   - ahci_xgene needs its own irq handler to work around a hardware
     erratum.  libahci updated to allow irq handler override.

   - Misc driver specific updates"
