    Phoronix: EXT4 With Linux 5.13 Looks Like It Will Support Casefolding With Encryption Enabled

    While EXT4 supports both case-folding for optional case insensitive filenames and does support file-system encryption, at the moment those features are mutually exclusive. But it looks like the upcoming Linux 5.13 kernel will allow casefolding and encryption to be active at the same time...

      I'm not a btrfs developer (I just follow their mailing list) but I don't recall to having seen anything related to that subject recently

        Thanks! Too bad. Integrating encryption to btrfs would probably be more difficult than for ext4. And considering the benchmarks I just looked up it would seem dm-crypt was - at least a few years ago - faster anyway. So probably it is not worth the trouble.

          Yes, btrfs over LUKS is quite fast and works well.
          I've been using that combo on all my desktops and notebooks for a decade now and I'm very happy with it.

            Same here. I merely wondered if not using luks would simplify the set-up.
