Hi,

assuming /dev/sda1 is an LUKS/dmcrypt encrypted partition. The default
elevator is "noop" (given in kernel command-line), but "cfq" is set
for /dev/sda in /sys/block/sda/queue/scheduler.

What elevator is used for the underlying /dev/mapper/dm-0 (sda1)?

sys/block/dm-0/queue/scheduler contains "none", btw.

Thanks,
Heinz.
