Anton Ivanov f88f0bdfc3 um: UBD Improvements ...

UBD at present is extremely slow because it handles only
one request at a time in the IO thread and IRQ handler.

The single request at a time is replaced by handling multiple
requests as well as necessary workarounds for short reads/writes.

Resulting performance improvement in disk IO - 30%
