Hello,
In our setup, we created a dedicated real-time section on top of RAID0
(backed by multiple SSDs). The rest of the filesystem resides on another
device.
When we ran the "fstrim" command on the mountpoint (mounted with -o
rtdev=/dev/md/raid), the discard does not propogate to the real-time
partition, and only the partition with metadata gets trimmed.
Is there a solution to this?
Best regards,
Konst

We are using Linux 5.15, by the way.
