ssd optimisation "none" scheduler in /sys/block/sdc/queue/scheduler

Hello,

I’ve noticed that there’s no “scheduler” in /sys/block/sdc/queue/scheduler anymore.

See:


new-host:/sys/block/sdc/queue # cat /sys/block/sdc/queue/scheduler
none
new-host:/sys/block/sdc/queue #

How can I see if I use cfq or deadline or noop… ?

N.B: I use kernel 3.18.1

Thanks

This seems to be a bug in kernel 3.18:

Thanks for highlighting that. Not a bug actually, but a new feature…
