There's a whole mess of CONFIG_CGROUP_* variables, feel free to turn off those that your system doesn't actually need. Make sure that you keep a backup kernel in case you turn off something you shouldn't have. In particular, systemd seems to want all sorts of cgroups for no reason other than "because they're there". --==_Exmh_1564367865_8191P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Comment: Exmh version 2.9.0 11/07/2018 iQIVAwUBXT5b+QdmEQWDXROgAQJ0gA/9EZeVO0OBFIi/7lw5wJk8ohy6r5ZkGFky Qu5XJqiPh7/9yFLjOZ3zZlGji0YzhTbh/U1bA0DyLBeD03xuilLF/dLICO9PoLz0 ce7ERkKz9fScN9dkw+4nwQErJ3fV3ZQN4tZfYIgWIGAPSuqVfvgKek+kcAmZkPhP +yaC7GMr18YaXnFZ7Cy/3La6l41tK5jTK4J6X2gwE3lbKA16IRUHF6z2ElMR4eoK s8S/N6324jwzJHm2fR1xTVWMU0uOZw9/4fjOcL7L0lRHLZFv2MntIpPavf1waOdm gwFqAUt+PXjt8K0BblxBtd8kz4Pa1EsRyDDYQA1Ub58X1XDxvGAAf2T1O/D6oUsv R1Oo44yDn4J5nHgZCPGfNjUc71FJkQZ90h9tHrYJAzlHbsHjKNsvNQz+pCKfZbWP g42M35b2DGuAl+q8kcJAdAXX09TmEv9r4nVhH/lJdRMXWR2Lf5gdPDyXqQAwL87M mQtXPJWTauyUks+7arna4FtshyvniAnpvvFufmXUPp5U3KWOLEb7y5sITWOw/QZm AfudQyKYS+1xgzsYh/Kd5L6isU7j7afWu6iEcnNg3ZP1jZ0M2QpJiqrza0dyGqae f7igV/5tgWTmZ6OTupfdyrYzI9Wx0vYrnWaGOBIU7YN6GJiRCoQ9sIZZiqPm6HIx POvGJuY21KA= =h9x9 -----END PGP SIGNATURE----- --==_Exmh_1564367865_8191P-- --===============5863729116000173920== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies --===============5863729116000173920==--
