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