Hi all,

As you know, we've got blk-mq merged to kernel since 4.13,
introducing, in particular, BFQ — an multithreaded low-latency
desktop-oriented I/O scheduler, hopefully to eliminate the infamous
#12309 kernel bug.

So, I've tweaked a `60-ssd-scheduler.rules` udev rule (it did set
scheduler to `deadline` for SSD drives) and made it support blk-mq as
well, should it has been enabled in kernel command line; there it
There's a PR featuring this tweak at, hopefully it'd be merged.

Works well for me. Feedback is welcome.
