[Description]
In [1] two important fixes in BTRFS are listed:

reading shared and compressed extents after hole punching"
4ea748e1d2c9f8a27332b949e8210dbbf392987e "btrfs: fix deadlock between
clone/dedupe and rename"
Both of them were backported to stable kernels like 4.14.x and newer
5.0 releases, but both are missisng in Ubuntu's 4.15.0 and 5.0.0.

Possible data corruption.
