Apparently F2FS is the best thing invented to help our SSD performance since sliced bread.

Does anyone agree?  Disagree?

Presumably this would only really be useful for stateful partition, but then you'd need to figure out how to deal with encryption requirements atop it, right?  Didn't we just transition to ext4 encryption, and this would be throwing away that work?

A bit of a shotgun approach to the CC list here since I'm not sure who would lead this investigation.  adlr / xiaochu: I think you guys were looking at btrfs at some point in time, but that was for the root filesystem.
