Forcing resize: don't know

You can do it while fs is mounted

1) check partition size
sudo fdisk -l /dev/mmcblk0

if size is already max then continue with step 5

2) remove swap part if exists (should be partition 3)
sudo swapoff -a
and then run sudo fdisk /dev/mmcblk0 and remove swap part
don't exit fdisk

3) enlarge root partition (should be partition 2) and add new swap partition
start fdisk if not already running
The trick is removing the existing one and create a new one with exactly the same start block and max size minus 250M for swap part
Add swap partition, use rest of disk for this
save changes to disk and exit (command w)

4) reload partition table into kernel
run sudo partprobe
if partprobe complains anything, you have to reboot before step 5

step 5) resize root fs and add swap
resize root fs
sudo btrfs filesystem resize max /
sudo swapoff -a
sudo mkswap /dev/mmcblk0p3
sudo swapon -a
