I'd like to gain a solid understanding of what these three knobs do.
Could you explain that a little more?
My basic understanding of fifo_batch is:
1) fifo_batch is how many contiguous requests can be in
a "set"
2) we send out one write "set" for every two read "sets"
3) a seek works out to "seek_cost" contiguous requests,
cost wise, this gets subtracted from how many requests
the current "set" has left that are allowed to be used
