Given two severe bugs in four months, it does not require much thought 
to conclude that OpenZFS places data at risk.

OpenZFS seems to have taken over:

The FreeBSD 13.2-R installers are from April 7, 2023:

https://download.freebsd.org/ftp/releases/ISO-IMAGES/13.2/


The fix for OpenZFS bug #15526 was added to FreeBSD on December 7, 2023:

https://cgit.freebsd.org/ports/commit/sysutils/openzfs?id=117f55784d981833d6b51038afc215239382e651

https://cgit.freebsd.org/ports/commit/sysutils/openzfs-kmod?id=117f55784d981833d6b51038afc215239382e651


If I use a FreeBSD 13-2-R installer to create a new FreeBSD instance 
with ZFS file systems and without native encryption:

1.  Will the installed FreeBSD instance contain corrupt files?

2.  Will the installed FreeBSD instance contain OpenZFS bug #15526?
