--- Comment #3 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
It was added to force inlining of small helpers that outgrow limits when
building with gcov profiling:

https://github.com/torvalds/linux/commit/258e0815e2b1706e87c0d874211097aa8a7aa52f

(lack of inlining triggered a sanity check, as explained in the commit)


I am surprised that "flatten" blows up on this function. Is that with any
config, or again some specific settings like gcov? Is there an existing lkml
thread about this?
