Apologies if this information is available somewhere, but a quick scan at the list archives failed to clarify things for me. How production ready is the reflink/clone code? I saw a patch series in October for 4.19rc-something with many fixes ("fixes for serious clone/dedupe problems"), so I guess pre-4.19 kernels are not quite recommended yet? Is 4.19 OK for it? Thanks in advance for any hints. Pointers to where I can keep up to date with this besides the mailing list are also welcome. regards, iustin
