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.

Yup.

I'm all for it.

Cheers,

Hannes
