Btrfs Fscrypt Design Document

[Omar Sandoval <osandov@xxxxxxxxxxx>]

Hello,

I've been working on adding fscrypt support to Btrfs. Btrfs has some
features (namely, reflinks and snapshots) that don't work well with the
existing fscrypt encryption policies. I've been discussing and
prototyping how to support these Btrfs features with fscrypt, so I
figured it was high time I write it down and loop in the fscrypt
developers as well.

Here is the Google Doc:

Please feel free to comment there or via email.

Thanks,
Omar
