Subject: [PATCH 35/37] livepatch-patch-hook: fix kpatch-build error which do
|
||
not support ftrace

When using the kernel 5.10.0-60.18.0.50.oe2203 in x86_64, and chose the
|
||
livepatch with ftrace, it will show not support for this feature, which
|
||
is not allowed, the error displays as follows:
|
||
|
||
In file included from /root/.kpatch/tmp/patch/patch-hook.c:21:
|
||
/root/.kpatch/tmp/patch/livepatch-patch-hook.c: In function ‘patch_init’:
|
||
/root/.kpatch/tmp/patch/livepatch-patch-hook.c:606:8: error: implicit declaration of function ‘klp_register_patch’; did you mean ‘klp_enable_patch’? [-Werror=implicit-function-declaration]
|
||
606 | ret = klp_register_patch(lpatch);
|
||
| ^~~~~~~~~~~~~~~~~~
|
||
| klp_enable_patch
|
||
|
||
So fix this problem.
