This will be good for the workstation installed with the latest Fedora if it can use the volumes formatted with 4k and create them that way by default. If the user formats a disk such as a USB stick and tries to use it with any other GNU/Linux system with an older kernel, such as RHEL, they may be surprised. With the changes mentioned, will it be possible to have 4k as default for mkfs.btrfs unless the user manually overrides it? As far as I know, there are no problems using ext4 on ppc64el systems but as btrfs is now the default, some people may end up with the 64k block size if they do an install today using the current Fedora installer. Another hack: maybe the installer can just default to ext4 on this architecture until 5.12 is available.
