'perf kvm stat record/report' will use kvm_exit and kvm_mmio(read...) to

mmio read event more exactly, we add kvm_mmio_begin to trace the time when
mmio read begins, also,

We don't need to unlock the queue before put_device in scsi_request_fn()
If we trigger the -remove() function, It occur a oops from the caller.
So sdev reference count should not be dropped to zero here.
Also It was added before scsi_device_dev_release() was moved

Peter,
What's your opinion about the patch? We hit it when enabling Medfield Android

This patch would put AP to a loop.
Another method to fix it is just to enlarge the wait time, for example, from
2HZ to 10HZ.

This patch set is another effort to bring down the size of trace events.
Helper functions are used to remove duplicate code that is created
for each event by the TRACE_EVENT() macros. With a config that enables
707 events in the core kernel, the size is brought down 91,774 bytes!

From: Steven Rostedt srost...@redhat.com
The code for trace events to format the raw recorded event data
into human readable format in the 'trace' file is repeated for every
event in the system. When you have over 700 events, this can add up
quite a bit.

The code that shows array fields for events is defined for all events.
This can add up quite a bit when you have over 700 events.
By making helper functions in the core kernel to do the work

Thanks for cleaning up the driver. If I understand the code
correctly, the original author wanted to initialize wm_event once and
reuse it for multiple devices, and thus reference counted it with
