Hi,

For a medium term project, I'm thinking of working on transparent compression
for Btrfs. Please give any hints and comments on how we would want to go
about this, the features we would like to have and some common pitfalls to
avoid.

Is looking at how it's done in Reiser4, a good idea ? Can we allow the
compression algorithm be configurable on a per file basis, may be using an
xattr ? This, for example, would allow us to make a compromise between speed
and compression ratio.

Any other ideas welcome.
