@carlo.bertolli is there documentation regarding `llvm_omp_target_lock_mem` `llvm_omp_target_unlock_mem`? While reading the comments of this patch, I see that the API ensures that locked areas feature reference counting. But I have the following doubts. Should the API support locking memory buffers that were already locked (e.g., complete or partial overlapping)? What's the behavior in such a case?
