[PATCH v3 0/8] [RfC] fix tracing for modules

[Gerd Hoffmann <kraxel@redhat.com>]

First version that actually works.  Only qxl covered for this RfC,
other modules will follow once the basics are hashed out.

v3:
 - handle initialization of modular tracepoints.

TODO:
Enabling modular tracepoints via -trace cmd line doesn't work yet.
Guess we need to store the list somewhere for later re-processing.
Error handling is tricky, specifically the "tracepoint doesn't exist"
error.  Suggestions / ideas are welcome.

take care,
