Explanatory note on bionic-proposed (see comment #17):
The flaky fail set had a long tail (tests that failed just a few times).
Symptom:
---
The logs show the failure cause is output mismatch, because '/target'
failed to umount (busy), and it was logged; e.g.,
btrfs/027 [failed,
In comment #17, read:
Verification done for BIONIC-proposed. (see 4.15 kernel.)

This mainline commit, recently backported to [B,F,G] for this bug:
"btrfs: extent-tree: kill BUG_ON() in __btrfs_free_extent()"
introduces a compile warning.
The warning has been fixed in mainline by:

1) synthetic reproducer
The reproducer consists in a crafted disk/btrfs image and C test-case.
This has not been helpful.
In Bionic, the crafted disk/btrfs image does not even mount.
In Focal/Groovy it does mount, but the test-case does not trigger any errors.
Anyway, the behavior is the same
2) stress-ng --class filesystem,io
Compared the stress-ng output and kernel log between original/patched kernels.
No regressions.
Actually, in Bionic the original kernel didn't even finish stress-ng in ~20
hours, while the patched kernel finished it in ~1.5 hours (in line w/ other the
