If not, why to increase BLK_MAX_BLOCK_SIZE further? Do you agree > that this question should be answered in the patch description? Do I agree that we should use the commit message to enter into a philosophical debate about whether ZNS or large block sizes are better? No, I do not. I don't even think we should have this discussion any more on this mailing list; I think everyone is aware that both alternatives exist. You don't like it, and that's your prerogative. But at some point you have to stop being an awkward cuss about it. I think CXL is an abomination; I've made this point often enough that everybody is aware of it. I don't make it any more. All I do is NACK the inclusion of patches that are only for the benefit of CXL until CXL has actually demonstrated its utility.
