[lttng-dev] Record stacktraces at userspace tracing domain

Hello,

we want to record stacktraces at specific userspace events like e.g. calls to malloc and free using liblttng-ust-libc-wrapper.so.
There is the callstack-user context to achieve this in general, however, it seems like tracing of userspace stacktraces is only available in the kernel tracing domain.

Is there already a solution to achieve this goal?
If not, what would need to be done to achieve this?

Thanks,
Alexander
