Meanwhile I have a working BCacheFS test setup on my laptop. Currently with 6.7-rc7. I can confirm on the longer than instant deletion times for almost 8 GiB large DVD ISO image files. It took 3,4 seconds for two of them. It appears to me that there is some optimization potential hidden in that. Best, -- Martin
