Thanks for testing and writing a patch! Unfortunately it breaks building 
a Buildroot system with selinux enabled on a non-selinux host, with 
error messages similar to the ones you saw building on an selinux host:

ERROR: zoned: unable to stat 
/home/fiona/development/buildroot/output/selinux/images/rootfs.btrfs

linux 6.1):

ERROR: error while filling filesystem: Operation not permitted

I assume the first line (zoned error) is a red herring, because it also 
appears in a btrfs image build that works fine. Same build without your 
patch produces:

I have sent a v3 with that update.
