[lttng-dev] [PATCH lttng-tools] Enable additional kernel probes

[Yannick Brosseau]

Just wondering, would it be possible to have an autodetection mechanism
to load all available probe module?

(or having a configuration file for this list?)

I'm thinking of the use case of people who would not want to load all
modules or provide a custom probe module.
