now, linux kernel ext4/f2fs filesystem can support casefold. i used this
commond to format ext4 filesystem.
mkfs.ext4 -F -O 64bit -L '' -E encoding=utf8 '/dev/block/nvme1n1p1'
but grub can't found vmlinuz and initrd.img on casefold ext4 filesystem.

Since casefolding is an INCOMPAT feature (c.f.,
https://elixir.bootlin.com/linux/latest/source/fs/ext4/ext4.h#L2034 ), and grub
does not implement that feature, grub will not be able to read such a file system.
Feel free to implement the feature, patches welcome and the like.
