Hi, I have tested the package in a virtual machine on amd64 for linux/4.19.37-3 (buster) and a locally built updated linux kernel that breaks zfs-linux/0.7.12-2. The dkms package builds fine with both of the versions and zpool create/export/import works fine. Therefore, please unblock the t-p-u update for buster, thanks. Regards, Aron
