We're planning supporting GCC LTO Linux kernel support, so that's one
motivati
Hi, Martin:
I have two questions on this:
1. What’s the motivation to enable -flive-patching with -flto? Is there any
application that will try -flive-patching with -flto now?
2. Why only enable -flive-patching=inline-clone with -flto?
thanks.

There's no fundamental reason why -flive-patching=inline-clone can't
coexist with -flto. Yes, one can theoretically have many more clone
function that includes a live patch. It is pretty much the same
as in-module inlining.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
