Hi all, I'd like to attend LSF/MM and would like to discuss polling for block drivers. Currently there is blk-iopoll but it is neither as widely used as NAPI in the networking field and accoring to Sagi's findings in [1] performance with polling is not on par with IRQ usage. On LSF/MM I'd like to whether it is desirable to have NAPI like polling in more block drivers and how to overcome the currently seen performance issues.
