btrfs has several differences from other filesystems currently integrated with fscrypt. It uses a newly proposed extent context object; only works with direct key policies; and allows partially encrypted directories. The design document can be found at [1]. As such, this splits a couple of tests and filters encryption policy printing to account for different filesystems' different default policies. Tests for subvolume encryption, a key feature for btrfs, are not yet complete. Necessary btrfs-progs changes are available at [2]; kernel changes are available at [3].
