This much smaller patchset can be fetched from github:

These patchset is targeted at v5.15 merge window.
There are 11 subpage enablment patches pending for a while, and not
touched, thus they should be pretty stable and safe.

While there are 7 new patches, 4 of them are straightforward small
fixes, the remaining 2 are a little scary as they reworked the core code
of compression.
The final new patch is a special write path hotfix, aiming to make btrfs
subpage writeback more robust against tests like dm-dust.

The rework should improve the readabilty thus make reviewing a
little easier (as least I hope so).

The series is in a topic branch and I'll move it to misc-next after one
more round of fstests, yesterday's testing was ok. Some of the changes
are scary but I haven't seen anything obvious and once it's in misc-next
it'll get more exposure so we'll be able to fix the remaining bugs.

Please send any fixups either as separate patches or let me know where
to do some simple tweaks. Thanks.
