load_certificate_list() parses certificates embedded in the kernel
image to load them onto the keyring.

Commit "2565ca7f5ec1 (certs: Move load_system_certificate_list to a common
function)" made load_certificate_list() a common function in the certs/
directory. Now, export load_certificate_list() outside certs/ to be used
by load_platform_certificate_list() which is added later in the patchset.

This lacking fixes tag, if it is a bug, or "reported-by" needs to be
completely removed.

Also, please describe the specific use it will be used. Patchset is not
a valid cross-reference in this context.

The specific usecase scenario is described in the cover letter.  Is
that what you're looking for?

thanks,

When I posted my first version for this patch set, kernel test robot 
reported the build error - 
https://lore.kernel.org/linux-integrity/202109110507.ucpEmrwz-lkp@intel.com/

The Reported-by tag is because of this statement in the reported error - 
" If you fix the issue, kindly add following tag as appropriate 
Reported-by: kernel test robot <lkp@intel.com>"

Do you still think that the tag is not required ? If so, I am fine to 
remove it.

Thanks & Regards,

      - Nayna

You cannot refer to "a patch set" in the long description. It's by all
practical means a dead ref after some years. The commit messages are
meant for commit log to help to understand the history of changes.
This does not do that job. Neither a cover letter helps with this.

It makes absolutely no sense for anything that is not triggered by the
mainline code.

I.e. if it is not merged, there is no bug.
