When reading in a page, eCryptfs would allocate a helper page, fill it with encrypted data from the lower filesytem, and then decrypt the data from the encrypted page and store the result in the eCryptfs page cache page. The crypto API supports in-place crypto operations which means that the allocation of the helper page is unnecessary when decrypting. This patch gets rid of the unneeded page allocation by reading encrypted data from the lower filesystem directly into the page cache page. The page cache page is then decrypted in-place.
