Subject[PATCH BUGFIX IMPROVEMENT 0/7] boost throughput with synced I/O, reduce latency and fix a bandwidth bug
Date
Hi Jens,
this series, based against for-5.3/block, contains:
1) The improvements to recover the throughput loss reported by
Srivatsa [1] (first five patches)
2) A preemption improvement to reduce I/O latency
3) A fix of a subtle bug causing loss of control over I/O bandwidths

Thanks,
Paolo
