Bug Description

When running zfs diff it can take a couple hours in an environment with lots of files/directories.

Is it possible to pull in this patch: https://github.com/openzfs/zfs/pull/10391

To address that issue?

Using ubuntu 20.04 at the moment.

As per the Stable Release Updates policy this needs to land in 20.10 first and then I'll backport it to 20.04. Currently ZFS 0.8.4 is working it's way into 20.10, so I expect to work on this issue next week.

From the look of it that fix is blocked in the review stage, can you update this bug once it's actually been reviewed, successfully tested and applied to the ZFS repo?

There has been no progress on the upstream fix, I've asked in the upstream bug report what the current status is for the fix.
