Subject: btrfs reports bad key ordering after out of memory situation

Hi Chris,
after reducing all partition sizes to 2TB I run my system now since 3 months without any problems. Many reboots and still very stable. Yesterday I run into a situation where I run out of memory on my 48Gbyte Virtual machine and suddenly the home partition was mounted read only. After a reboot the system did not come back.
I did a btrfs check —readonly /dev/sda2 and it reported
btrfs restore -l /dev/sdb2 test
tree key (EXTENT_TREE ROOT_ITEM 0) 278911795200 level 2
tree key (DEV_TREE ROOT_ITEM 0) 279226892288 level 0

bad key ordering 192 193
bad key ordering 192 193
tree key (DATA_RELOC_TREE ROOT_ITEM 0) 43673436160 level 0
Could you please help me to repair this system?
Which command I can use ?
For the btrfs restore command I used the newest btrfs version.
The btrfs version the system was running on is 4.19
Thanks a lot,
Chris
