Hello, i suggest temporary solution to use swap file under btrfs.
I test it, and it work good.
I invent simple the way, how create and using swap file, just see
following sh code:
swapfile=$(losetup -f) #free loop device
truncate -s 8G /swap #create 8G sparse swap file
losetup $swapfile /swap #mount file to loop
mkswap $swapfile
swapon $swapfile
i just adding this to rc.local and this work good.
May be, add it to btrfs Wiki as temporary solution to using swap file?

Hi,
Yes, Timofey, it does work. I tested the same over a year ago. And it
does say briefly about this option in wiki
https://btrfs.wiki.kernel.org/index.php/FAQ#Does_btrfs_support_swap_files.3F
"A workaround, albeit with poor performance, is to mount a swap file via
a loop device."
