The patch looks fine, but the patch description could use some rewriting. The IMA/EVM attributes are currently stored in the "security" namespace, which requires root privileges.  Storing the ima/evm attributes in the "user" namespace, instead of the "security" namespace, would be useful for testing purposes.  Please expand this: "and because --sigfile does not work for evm signatures." Conclude with, this patch defines the "--xattr-user" option for testing. Mimi
