However, it looks a bit
complicated, and I was thinking if one simpler approach can be
figured

out.

I was thinking your original approach is simple, but if you think some
other simple approach I can test as part of these series.
BTW, I am still not getting why you think your original approach is
not good design.

It is still not straightforward enough or simple enough for proving its
correctness, even though the implementation isn't complicated.

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.
