I used to track such bugs on the Debian wiki page for Btrfs...but users
of Debian and derivatives continued to track
sid/testing/stable-backports kernel, which made me feel like that work
was a waste of time.  Now that page has a warning that reads something
along the lines of "sid/testing/backports kernels periodically have
grave dataloss bugs.  Please track the most recent upstream LTS kernel
if a kernel newer than 4.19.x is required.  That said, upstream
appreciates bug reports using the most recent kernel available to you".

If you'd like to maintain a section at the top of that page that tracks
this type of issue, please go ahead.  I'd rather work on getting boot
environments working properly, then making them easy to use, then
enabling staged upgrades in a rw snapshot before rotating that snapshot
onto the rootfs.

P.S. Do you want to co-found a BTRFS integration team in Debian?  We're
still quite a ways behind SUSE, and even Fedora is ahead of us now!

Regards,
Nicholas
