Request for copyright assignment form

Hi,

I have never contributed to gdb but am interested in
contributing to it in the long run.

I have one patch ready [1] and have been informed that
I'll need to complete a "copyright assignment" process
before the changes can be merged. I found this request
form [2] for past and future changes in gnulib's repo.
I am not sure if this is just a sample form or if it's
appropriate for gdb-related changes.

Where might I find the relevant FSF copyright assignment
request form?

Thanks,
Sahil
