Regression testing done with 3 approaches:

1) synthetic reproducer in kernel.org BZ#202833 [1]
2) stress-ng --class filesystem,io
3) xfstests (aka fstests)

No regressions observed in Bionic/Focal/Groovy between original/patched kernels, in s390x native VMs in canonistack-bos01.

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 in the original/patched kernels.
No regressions.

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 releases.)
Thus it's apparently an improvement.

For documentation purposes, this seems to be due to the 'fiemap' stressor in the 'filesystem' class, which had defunct processes when I checked before cancelling the tests:

3) xfstests (aka fstests)

Compared the 'consistently fail set' and 'likelyhood to fail' in flaky tests (see below.)
No regressions.

Details:
---

Source:
- git://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git
- commit 31f6949f ("ext4: verify unwritten extent conversion in buff-io")

The test set is the 'full' suite (default), not just the 'quick' group/suite.

The fail set is flaky (some tests fail/pass inconsistently), so the 'consistently fail set' (i.e., fail every time) across 10-20 runs has been compared between the original/patched kernels.

Also looked for increased likelyhood to fail (i.e., flaky tests that fail more often with the patches.)

More Details:
---

The xfstests output/log includes the fail set in the 'Failures:' line, and the kernel version in the 'PLATFORM' line.
For example:

$ grep -e ^Fail -e ^PLATFORM xfstests.log.2020-10-27-13-26-44
PLATFORM -- Linux/s390x mfo-s390x-focal 5.4.0-52-generic #57-Ubuntu SMP Thu Oct 15 10:52:40 UTC 2020
Failures: btrfs/153 btrfs/200 btrfs/204 btrfs/205 btrfs/213 btrfs/220 btrfs/221 btrfs/222 btrfs/226 generic/166 generic/175 generic/260 generic/286 generic/301 generic/465 generic/484 generic/610

Those two lines from each log/run are used to identify, per kernel version (original/patched):
- how many runs have been done;
- which tests fail consistently (i.e., in all runs);
- which tests fail inconsistently (i.e., flaky) and how many times (to compare likelyhood to fail)

In Focal there are 8 regressions between master/bionic-updates and master-next/not-yet-bionic-proposed (i.e., caused by other 13 btrfs patches; _not_ this patchset.)

However, there are 0 regressions between master-next and master-next + this patchset. So, this patchset is good.

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:
cad69d139651 btrfs: tree-checker: fix incorrect printk format
so let's pick up that fix too.

Verification done for focal-proposed.
No regressions in the consistent/flaky fail sets.

The flaky fail set had a long tail (tests that failed just a few times),
but it can be isolated to another btrfs commit, and it doesn't seem to
happen often. (e.g. not seen on focal-proposed, but seen on focal orig
kernel on master-next, and both have the commit.)
Thus not a general/permanent issue. More details in the next comment.

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, exit status 1]- output mismatch (see /home/ubuntu/xfstests-dev/results//btrfs/027.out.bad)

The number of failed tests increases with the number of umount failures.

After these errors, the failure rate increased; but not all times/tests;
since it seems that at some point the umount finishes, unblocking tests.

Cause:
---

Since this issue didn't happen with the test/patched kernel, it would
seem to originate from other/new patches. There are indeed 2 new ones
not used in the test kernel:

The commit message in 6f64bf0873eb explicitly describes the umount path
(now in return to userspace, but still.)  So it does look like a match:

Also, this issue happened with Focal's original kernel from master-next,
which happened to have that commit already; and it didn't happen with
Focal's 'pre-original' kernel from -updates, which didn't. More evidence.

Revert?
---

Apparently this doesn't need to be reverted; it doesn't happen everytime,
as seen in this test, and with previous tests for Focal:

As described above, this was also noticed in Focal's results w/ the original
kernel from master-next, which has that commit, but to a lesser extent (see 
comment #8) so it wasn't noticed as much.

Thus the impact seem to vary, and happen more rarely, because the results w/
focal-proposed did NOT hit it a single time in 11 runs, and commit IS there.
