These patches fix the UST backend which got broken by LTTng 2.x. An interesting new feature in LTTng 2.x is that tracepoints now need to belong to a provider. A provider is a way to group tracepoints in a logical way, for instance tracepoints that belong to a specific file or subsystem. This would then allow users to enable all tracepoints of a specific provider at once.
In these patches, only one provider is defined, which is called "ust" (and tracepoints are defined in generated-ust-provider.h). It would be interesting to take advantage of this feature in the future, separating tracepoints into multiple providers. Of course, this would require more modifications as well as a way to specify to which provider each tracepoint belongs in file trace-events. Mohamad Mohamad Gebai (3): Fix configure script for LTTng 2.x Modified the tracetool framework for LTTng 2.x. Adapt Makefiles to the new LTTng ust interface.
