I agree we should fix this, nevertheless I don't expect this to
create an IO rate issue for long queue depths.
Indeed we will have a tradeoff here of latency vs rate.
I suggest we hold back with this one for now, I have fixes for
the local invalidate flow. Once we get them in we can see if
this approach makes a difference, and if so, we need to expose
it through a generic mechanism.
I suggest that you'll post the patches to the list and we'll investigate
the latency implications, if the implications are negligible, we have a
win here for small IOs.
When will you be able to post your patches?
