Without a long-term agreement between the Linux Kernel and the OpenZFS
project the whole community will suffer. Opensource is about finding
paths to collaborate.

Now lustre is based on ZFS, this kernel regression will impact the HPC
community.

I'm not a lawyer, but I think that OracleZFS benefits from the
improvements made by OpenZFS. If there is an agreement between the
Linux Kernel and the OpenZFS project to convert OpenZFS to GPL, then
Oracle won't benefit any more from OpenZFS and they will be forced to
release the original ZFS code as GPL.

Below you can find an excerpt from the GitHub discussion.

I understand that ZoL would like to convert OpenZFS to GPL, but they
will need the help and support of the Linux Kernel developers.

This Linux kernel regression will break lot of computers and people
might loose data. Most of the users will have no clue why their
computer is not working and will blame Debian and the opensource
software.

Best,
