Latest maintenance update on kernel (4.4.70-18.9-default) is causing one of my
btrfs partition to not be mountable at all:

[    4.125164] BTRFS info (device sdb1): disk space caching is enabled
[    4.132807] BTRFS error (device sdb1): super_total_bytes 1000203816960
mismatch with fs_devices total_rw_bytes 1000203820544
[    4.132809] BTRFS error (device sdb1): failed to read chunk tree: -22
[    4.169764] BTRFS error (device sdb1): open_ctree failed

kernel-default-4.4.62-18.6.1.x86_64 is able to mount it properly.

I ran scrub and balance on it from kernel 4.4.62-18.6.1, no error found :
