No. You need to be submitting the code that will use the symbol *at
the
same time* as the patch to export the symbol. No example code
showing
how it could be used. Because if the user isn't compelling, the
patch
to export the symbol won't be applied either.

Hi Matthew,

Got it. The following attached patch file
"v1-0001-memory-export-symbols-for-process-memory-related-.patch" is
the patch including the users of these new symbols. Thanks.

Please send both patches as a single series, then we can start review process. I had a very quick look on the attached patch and it's missing a good commit message describing what the drivers is for and why you need it.

Regards,
Matthias
