[PATCH 0/2] block: Keep filter children attached during drop

[Wesley Hershberger <wesley.hershberger@canonical.com>]

Thank you all for the discussion in the previous thread:
20251024-second-fix-3149-v1-1-d997fa3d5ce2@canonical.com

I have verified that this patch resolves the issue from #3149 and passes
the iotests for qcow2/raw/nbd that don't fail on master (for me). Thanks
for the pointers on testing.

I'm committed to finding a solution to this that is adequately
understood and tested; I'm happy to continue to make
adjustments/submissions as needed until we have a solution that is
satisfying.

Please let me know if any adjustments are needed; thanks for your
patience and continued involvement.
