[dm-devel] Trying to us dmcache with zram block device

[Akira Hayakawa]

Hi,

Sorry to interrupt.

A similar issue is reported with dm-writeboost and zram cache device.
The bug there is that metadata read failed in initialization.

Do you have some advance on this issue?
I am wondering if it's device-mapper that misbehaves.
