[Discussion] HyperCache is it still flashcache under the hood?  [SOLVED]

I am an advanced linux technical guy, is terramaster TOS 6+ "Hyper Cache" still using Facebook's deprecated `flashcache` block caching technology or has this transitioned to something else?

If its no longer flashcache what is it, linux-bcache? lvmcache?

If support ignores this question could someone with hypercache enabled share output of the following linux commands in terminal as root:
- dmsetup status
- dmsetup ls
- dmsetup table
- lvs -o vg_name,lv_name,lv_attr,data_percent,metadata_percent
- lsblk -o NAME,TYPE,MOUNTPOINT |
- ls /sys/fs/bcache/
- lsmod | grep -e flashcache -e bcache -e enhanceio
- cat /proc-cmdline
