From: Nadav Amit <namit@vmware.com>

Functions that are marked as "inline" are currently also not tracable.
Apparently, this has been done to prevent differences between different
configs that caused different functions to be tracable on different
platforms.

Anyhow, this consideration is not very strong, and tying "inline" and
"notrace" does not seem very beneficial. The "inline" keyword is just a
hint, and many functions are currently not tracable due to this reason.

Disconnect "inline" from "notrace".
