| 16 | Say Y here if you want to support kernel live patching. |
| 17 | This option has no runtime impact until a kernel "patch" |
| 18 | module uses the interface provided by this option to register |
| 19 | a patch, causing calls to patched functions to be redirected |
| 20 | to new function code contained in the patch module. |
