* Commit your bugfix
* 'git send-email --to=git@vger.kernel.org -1'
With the GNU model:
* Commit your bugfix / make a patch
* Send your patch to the maintainer of the project
* The maintainer has to look in a central file if you already assigned copyright to the FSF
* If not, they send you an email 'would you be willing to do this'
* You reply, "sure, send me the form"
* They send you this: https://gforge.inria.fr/scm/viewvc.php/misc/www/request-disc...
* You fill in the form, and thus hand over your snail mail address to the maintainer and the FSF
* They send you another form (snail mail!)
* You fill it in and send it back (snail mail!)
* They receive your form and add it to the list
* Your bugfix is now allowed to go into the GNU repository
