Hi,

I hope this is the right list. I am maintaining the package openafs on the OBS which contains a KMP. (https://build.opensuse.org/package/show/filesystems/openafs)

I was (locally) trying to insert "-mindirect-branch=thunk-extern -mindirect-branch-register" at various places and compiling with gcc-8.

However, on loading the module the kernel always complains :

" libafs: loading module not compiled with retpoline compiler."

What is the correct way to compile an external KMP with the retpoline ?

Many thanks,

Christof
