Do you think this patchset can be applied? If so, When? Perhaps you
are waiting for someone's feedback?

We've also tested and got the duration could be shortened from 6m26s
to 44s when 'eh_deadline' was set as 1s(the minimum value of timeout)
and 16M data were written(I/O processing time can be ignored - 0.7s).

As Ewan said, this is efficient to fast failover policy for redundant
environments.

Thanks,
Ren
