Lidong Chen 1cf6aa74b3 migration/block: Avoid invoking blk_drain too frequently ... Increase bmds->cur_dirty after submit io, so reduce the frequency involve into blk_drain, and improve the performance obviously when block migration. The performance test result of this patch: During the block dirty save phase, this patch improve guest os IOPS from 4.0K to 9.5K. and improve the migration speed from 505856 rsec/s to 855756 rsec/s.
