[PATCH] eCryptfs: Encrypted passthrough
Provide an option to provide a view of the encrypted files such that the metadata is always in the header of the files, regardless of whether the metadata is actually in the header or in the extended attribute. This mode of operation is useful for applications like incremental backup utilities that do not preserve the extended attributes when directly accessing the lower files. With this option enabled, the files under the eCryptfs mount point will be read-only.
