Hi Kent,

I read your bcachefs snapshots doc recently, it looks like you've put a 
lot of thought into it.  Is it ready for testing?  

We use a lot of btrfs snapshots of VM images but the performance is pretty 
poor and I'm looking forward to trying out bcachefs snapshots when it is 
ready to try out.

We also have many dm-thin deployments backed by /dev/bcache0 volumes that 
work quite well, but dm-thin meta is always an ongoing maintenance issue.
(Don't run out of dm-thin meta space or *boom*!)

If bcachefs can replace dm-thin with loopback files (or even better, 
native bcachefs devices!) then I look forward to getting beyond
dm-thin into something more scalable.

Cheers,

-Eric
