btrfs-convert doesn't work

[solskogen]

This is special for the Pi5.
btrfs-convert cannot be used because of the page size.
` btrfs-convert /dev/mmcblk0
btrfs-convert from btrfs-progs v6.2

WARNING: blocksize 4096 is not equal to the page size 16384, converted filesystem won't mount on this system`

Normal mkfs.btrfs works.

Yes, the same is true of F2FS. If btrfs is important to you, put kernel=kernel8.img in config.txt to use the Pi 4 kernel.

Yeah, it was more like a FYI rather than a bug. I noticed this when I got my Pi5 yesterday and my old sdcard didn't boot.
