`btrfsck -s1 /dev/sda4` gave errors too.=20
So i skipped to running btrfs-zero-log. It ran without errors.
But running btrfsck again still gave the same errors.

So i went back and tried btrfs-select-super...

# ./btrfs-select-super -s1 /dev/sda4
using SB copy 1, bytenr 67108864

After this i tried mounting and it worked for all subvolumes!
I am ever so grateful for your help Fajar.
=20
Unfortunately I didn't try mounting after the btrfs-zero-log so i don't
know if it or btrfs-select-super was actually the cure.

Knowing very little about zero-log and select-super should i continue
using my laptop like normal now?
Or is this filesystem still considered corrupt and i should backup and
format it all from scratch?
