Hello Shaohua,
My understanding of this work is that a significant part of it will have to be reverted once blk-mq supports I/O scheduling, e.g. the code for detecting whether the I/O submitter is idle. Shouldn't this kind of infrastructure be added after support has been added in blk-mq for I/O scheduling?
Thanks,
Bart.
