Maybe someone can help me understand the log file here. I just setup a ZFS pool a few days ago and yesterday moved my docker containers on that new pool. Today I am seeing errors in the system log. Are they ZFS related or is it because today I got a notification for an update to RC2?

This is a common call trace, unrelated to zfs, and it should be harmless, most users get it, including myself, it should only happen once per boot, but it can show up soon or after a week or more.
