Bug Description
ZFS version 0.7.12 has a documented very severe regression on sending and receiving datasets with dnodesize=auto set on the dataset (not present in 0.7.9 or 0.8.1). This manifests itself primarily when sending and receiving datasets with lots of files, such as happens if root is on ZFS. This issue has been documented on the ZFSonlinux git repositories in issues:

Since 0.7.12 was just brought into 18.04.3, this regression is now affecting LTS. I'm opening this issue in the hopes that the fix is backported to the LTS release

I can confirm on a Lenovo M920S and Lenovo Thinkpad X1 Carbon, both with 18.04.3 and zfs package version 0.7.5-1ubuntu16.6
