We hit the following hiccup a couple times in the past few months:
A function is marked as "inline", but the compiler decided not to inline it.
Since "inline" implies "notrace" since [1], this function doesn't have
fentry/mcount. When we built livepatch for this function, kpatch-build
failed with:
xxx.o: function yyy has no fentry/mcount call, unable to patch
This is not a deal breaker, as we can usually modify the patch to work
around it. But I wonder whether we still need "inline" to imply "notrace".
Can we remove this to make livepatch a little easier?
Thanks,
Song
