[PATCH v7 20/43] btrfs: add fscrypt_info and encryption_type to ordered_extent

[Daniel Vacek <neelx@suse.com>]

From: Josef Bacik <josef@toxicpanda.com>

We're going to need these to update the file extent items once the
writes are complete.  Add them and add the pieces necessary to assign
them and free everything.
