Then yeah, we're probably looking at 5.12, since it's ~80 patches last
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
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
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
