The comment for fscrypt_encrypt_page() still says the following: * Called on the page write path. The caller must call * fscrypt_restore_control_page() on the returned ciphertext page to * release the bounce buffer and the encryption context. It seems this isn't correct anymore. It also looks like the fscrypt_context never gets released in the case where the page is encrypted in-place. Additionally, after this change the name of the flag FS_WRITE_PATH_FL is misleading, since it now really indicates the presence of a bounce buffer rather than the "write path". Eric
