blktrace on my block device

[Gangadhar Mylapuram <gangadhar.m@xxxxxxxxx>]

Hi,

As for my understanding I no need to handle (BLKRESTART, BLKTRACESTOP,
BLKTRACESETUP ..) in my device ioctl handling. It is block l/O layer
which intercepts the
statistics and does the job.

But for my device (not sda or hda), blktrace only show the Q events.
It is not showing even C (completed) events. Do I need to add the
support in my device ioctl handling code?

Thanks,
Gangadhar
