Ming -

I noted your comments.

I have completed testing and this particular latest performance issue on
Volume is outstanding.
Currently it is 20-25% performance drop in IOPs and we want that to be
closed before shared host tag is enabled for <megaraid_sas> driver.
Just for my understanding - What will be the next steps on this ?

I can validate any new approach/patch for this issue.
