Hi Mike, Bart and Guys,
I know there is a hole in blk-mq about RESTART, will post a patch soon if
it can be done before my flight, otherwise you should see the patch at
your tomorrow.
And just take a quick look at Bart's debugfs log, my patch should
address this issue, but we need to discuss about the solution a bit, and the
patch will be marked as RFC.
Thank,
Ming
