Awesome! Really awesome!
I am running BTRFS on a ThinkPad T520 since at least 2014. After all
these initial free space related issues went away with linux 4.5 or 4.6
I had no issues with it anymore. In part I use BTRFS RAID 1 with an
mSATA SSD on the laptop and it recovered from what I believe had been
power loss related errors on the mSATA SSD twice already. Of course that
is not anywhere near the dimension of errors the filesystem you have
experienced.
I use it on my backup drives and I use it on my server VMs.
It works for me.
Best,
