Realistically, when can we expect this on fresh installs of Debian or Fedora? Will desktop users notice a perceptible performance gain when performing operation

Realistically, when can we expect this on fresh installs of Debian or Fedora? Will desktop users notice a perceptible performance gain when performing operations on large files?

Fedora has switched to btrfs, but you can still choose your own preferred filesystem at install, just as you have always been able to.

  i mean, my Fedora system will be on ext4 for a while since I don't wipe anew with every upgrade...

  That's just the desktop "spin", albeit that is the default download. Personally, it's gonna be some time before I'd switch to btrfs if ever.

    Why is that?

      For me personally, I am waiting for ENOSPC to be 100% solved and understood. It may or may not be (maybe it's theoretically impossible to solve who knows), but until then I'm content with what I have now.

        > I am waiting for ENOSPC to be 100% solved and understood It's understood, there's no black magic. When there's not enough contiguous space to perform a metadata copy (it's a copy on write filesystem, no in-place overwrites!) then it returns an error, even if there's still some free but fragmented space or some free space in the data block groups. A rebalance when metadata blockgroup total size diverges significantly from actual use should solve this. For small filesystems there also is the option to choose mixed block groups, then there won't be the situation where there's still free space in the data groups while the metadata groups are full.

Not that far for Fedora since they're already on 5.9 and if you opt in for the kernel stabilisation COPR, you can have it today: https://fedoraproject.org/wiki/Test_Day:2021-01-04_Kernel_5.10_Test_Week https://fedoraproject.org/wiki/Test_Day:2021-01-04_Kernel_5....

  not sure how it relates to fedora, but article also points out you need to mkfs to build a new structure and the patch to build it hasn't hit ext2progs mainline yet

    Is there no other way to convert existing ext4 filesystems to use the new structures?

  Correction: Fedora has already rolled out 5.10 on Fedora 33.
