Dear Rick,
It looks like your message is unrelated to the thread at hand.
Therefore, please start a new thread by *not* using the reply feature,

Hi Neil,
For the md higher write IO latency problem, I bisected it to these commits:
4ad23a97 MD: use per-cpu counter for writes_pending

Do you maybe have an idea? How can we fix it?

Jack Wang
