>ZFS L2ARC still has a bug that randomly evicts metadata cache despite being less than half full
what is the point of L2ARC if it culls itself all the time and i have to hit the HDDs anyway.
All i want is read-only metadata cache on optane, so stuff like ls, ncdu etc. are fast.
I don't want to set up and maintain a special vdev just for this...
