[lttng-dev] [LTTng UST PATCH 0/2] Bug fixes for callsite unregistering

[Ikaheimonen, JP]

The following two patches fix one bug each in LTTng UST.

The first patch makes sure that when a library registers callsites, those callsites are also properly unregistered.
It is only a matter of actually updating the list of callsites during registration.

The second patch deals with nested dynamic libraries. The current code disables tracepoints whenever a library destructor gets called.
But if those tracepoints are also used by some other open library, then they stop working.
The solution in the patch keeps track of how many callsites use a tracepoint, and disables the tracepoint only after the last library logs off.
To work, the first patch must be applied first.
