I will not use or recommend ZFS on _any_ OS until they solve the double page cache problem. A filesystem has no business running its own damned page cache that duplicates the OS one. I don't give a damn if ZFS has a fancy eviction algorithm. ARC's patent is expired. Go port it to mainline Linux if it's not that good. Just don't make inner platform.

That’s such a weird hill to die on. It’s like refusing to drive a car because it uses head bolts instead of head studs in an engine.
