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.

[Impact]
* Users of btrfs started hitting a kernel BUG() (below)
after upgrade from 4.15.0-99.100 to 4.15.0-109.110,
which has 55 btrfs changes.

* The error happens at random moments, regardless of a
particular activity/load. Workaround is to downgrade.
[Fix]
* This BUG()/function is addressed in patch 4/4 [1] of series
'btrfs: Enhanced runtime defence against fuzzed images' [2],
after issues in the real world, not just crafted fs images:
'one internal report has hit one BUG_ON() with real world fs'
kernel BUG at fs/btrfs/ctree.c:3188!
...
RIP: 0010:btrfs_set_item_key_safe+0x16c/0x180
* The patch/set [3] is applied in v5.10-rc1 and Ubuntu Unstable:
- d16c702fe4f2 btrfs: ctree: check key order before merging tree blocks
- 07cce5cf3b48 btrfs: extent-tree: kill the BUG_ON() in
insert_inline_extent_backref()
- 1c2a07f598d5 btrfs: extent-tree: kill BUG_ON() in __btrfs_free_extent()
- f98b6215d7d1 btrfs: extent_io: do extra check for extent buffer read
write functions
[Test Case]
* There is working synthetic reproducer for this issue,
which is hard to reproduce as reported in commit [4]
that introduces debugging for the issue.
* Regression tests with xfstests and stress-ng shows
no regressions between un/patched kernels.
[Other Info]
* Trivial backports (only refreshing a few context lines)
with 3 more dependency patches on Bionic and 1 on Focal.
And Bionic needed one extra hunk to '#include' a header.
Groovy all apply cleanly.
