As documented in SubmittingPatches please send patches to the=20 maintainers for the code you would like to change. The normal kernel workflow is that people apply patches from their inboxes, if they aren't copied they are likely to not see the patch at all and it is much more difficult to apply patches. --m51xatjYGsM+13rf Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl0koMsACgkQJNaLcl1U h9DKIAf/ZSDNvbMm/N+6RjKfnFdQwjyhpG6CS03BFIGfNvdDiHDfcIUOccR8kUSS hWzTKI/7f4jlLyaWXinkVc59G60+IS1+DbO8o2PCAQ3Fpciz5/c6F7BQrLy42Xal /icTrnVX0d/70ss5a7YT5yj67O7bItcRvbUuT8bDzHIIVzNWmXc8hMZYMTSB14DV fLs8tnfbR0SK4zjd2smCFHGieZBZquTeBjF2ZQlA0YS232MyNNBJCtmW52KUfbVn gBukHDwh9QkCJEAdFHknAMmcYPgBF0FXnBkMwhXKeCW9PAxHXK/PC+nqvanw4dmi ZVeeGKO4caaGNXi5unWwFznO4RwCFQ== =xlH7 -----END PGP SIGNATURE----- --m51xatjYGsM+13rf--
