Hi all, Apparently some bcache users are hit by the message in the subject, see https://bugzilla.redhat.com/show_bug.cgi?id=1922485 I personally cannot reproduce this, but if the provided info is correct, a certain kernel upgrade will break existing bcache setups. Is this really true? If so, this is a breaking change, which is very harmful. I hope some of you have suggestions for the people who apparently are impacted by this. Best, Rolf Fokkens
