write your patch against the latest libata tree available at:
git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata.git
or
https://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/libata.git
And use "git send-email" to send the patch to me and to linux-ide@xxxxxxxxxxxxxxx.
Feel free to let me know if you have any problem.
Thanks.
