Would the following ordering of the patch set be acceptable:

  => PATCH 0/5: Cover letter

  => PATCH 1/5: Define the enum "hook(BUILTIN_TRUSTED_KEYS)" in ima.h

  => PATCH 2/5: Define ima hook
                This will initially do nothing if ima is not yet
                initialized.
                Call process_buffer_measurement() if ima is initialized.

  => PATCH 3/5: key_create_or_update change and the call to ima hook

  => PATCH 4/5: Queue\De-Queue of key measurement requests.
                Enable queuing of key in the ima hook if ima is not
                initialized.

  => PATCH 5/5: ima policy to enable measurement of keys which will
                enable end-to-end working of this feature.
