Package: linux-image-4.9.0-16-686-pae
Version: 4.9.272-1
Severity: critical

This release introduce introduce an incompatibility in btrfs free space
cache which leads to an filesystem corruption!

The solution is simple but not obvious: Do a `mount -o
remount,clear_cache,space_cache /filesystem` as early as possible after
boot into the new kernel for every btrfs filesystem.

Please add a release note and a warning for the admin.
