The article does not mention bcachefs as a future alternative: http://bcachefs.org/
“Not quite finished - it's safe to enable, but there's some work left related to copy GC before we can enable free space accounting based on compressed size: right now, enabling compression won't actually let you store any more data in your filesystem than if the data was uncompressed.”
What is the point of having compression enabled if you can’t store more data than you could if it was uncompressed? Shouldn’t they just say “compression mechanism works but not useful yet. as of now it is just extra overhead”..
