I recommend reading the in-kernel documentation about all of this which
can be found at Documentation/process/submitting-patches.rst in the
kernel source tree. That should explain all of this and is recommended
reading first if you have questions about how to create and submit a
patch.
If after reading that, you have specific questions, please let us know.
