Source: linux-2.6
Version: 3.1.0-1~experimental.1
Severity: normal
I use dm-crypt on my system, and I have an SSD. The underlying disk
device, sda, has rotational=0:
~$ cat /sys/block/sda/queue/rotational
0
However, the device-mapper devices have rotational=1:
~$ head /sys/block/dm-*/queue/rotational
==> /sys/block/dm-0/queue/rotational <==
1
==> /sys/block/dm-1/queue/rotational <==
1
==> /sys/block/dm-2/queue/rotational <==
1
The device-mapper devices should inherit the setting for "rotational"
from their underlying devices.

As suggested previously, this bug seems fixed in 3.2:
~$ lsblk -i -o name,type,mountpoint,rota
NAME TYPE MOUNTPOINT ROTA
sda disk 0
|-sda1 part /boot 0
`-sda2 part 0
`-sda2_crypt (dm-0) crypt 0
|-leaf-swap (dm-1) lvm [SWAP] 0
`-leaf-root (dm-2) lvm / 0
Closing.
