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

8e928218780e2f1cf2f5891c7575e8f0b284fcce "btrfs: fix corruption 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.

[Impact]
Possible data corruption.

[Solution]
Cherry-pick those commits to supported kernels.
