This is a somewhat related set of patches that scratch some itches that I had after working on the migration to the ablkcipher API. They all relate to how eCryptfs is using the "helper page" during crypto operations. The helper page is the intermediary page between the lower encrypted page and the decrypted eCryptfs page. When decrypting, eCryptfs reads from the lower filesystem into a helper page. Then the helper page is decrypted and the result is stored in the eCryptfs page. When encrypting, eCryptfs encrypts its page and the result is stored in a helper page. Then the contents of the helper page are written to the lower filesystem. It is slightly more complex, as crypto operations aren't done across the entire page (that's where eCryptfs "extents" come into play). But the focus of these patches is how we're utilizing the helper pages.
