This looks like a useful feature for the hitachi driver.

The suggested feedback is minor and Atsushi has been very active in resolving feedback comments.

I would like to grant this feature an FFE.

Hi Team,

I'd like to request FFE for following patch:

*Hitachi: support data deduplication and compression*
Patch: https://review.opendev.org/c/openstack/cinder/+/850831
Status: Fix merge conflict and add unit test

Why missed the deadline is merge conflict when it occurred at the deadline day.
I'll upload this patch, which is rebased and fixed unresolved review comment, by Feb 21st.

This feature is useful for capacity saving, and is isolated to the Hitachi driver module, and have no impact on the Cinder database, REST/RPC and APIs.

Best regards,
Atsushi Kawai
