I applied this patch series to the latest upstream kernel and measured
the read/write throughput using it. So, I have not try Pavel's patch yet.

However, I think it is compatible with his write-back patch series
since it just makes maximum limit of fuse request size tunable.
And my patch will be effective even for direct I/O.

Thanks,
