Subject: Re: [RFC] blk-mq and I/O scheduling

Hi Andreas,

I don't understand the time slicing algorithm to well, but from the
blk-mq integration perspective this looks nice, and anything that
helps improving blk-mq for spinning rust is useful.

As a nitpick some of the larger "if (use_time_slice)" blocks should
be moved into separate helper functions‥
