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% Signed-off-by: Anton Ivanov <aivanov@kot-begemot.co.uk> Signed-off-by: Richard Weinberger <richard@nod.at>
