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.
