Hi Ray,
Thank you for information. Your analysis is right.
I also noticed same problem.
If you'd like to submit patch, not to report, please send it with regular form.
Or I could send similar patch I have.
Thanks,

Nowadays,the IO schedulers in linux kernel have four types:
deadline,noop,Anticiptory and CFQ.CFQ is the default scheduler.But CFQ is
not a good scheduler for SSD,dealine may be a good choice.
When deadline runs,it has a mount of computation about merging and
sorting.Merge has three types: front
