Mikhail Gavrilov 75f3cf0d15 rv: Fix multiple definition of __pcpu_unique_da_mon_this ... The refactoring in commit 30984ccf31 ("rv: Refactor da_monitor to minimise macros") replaced per-monitor unique variable names (da_mon_##name) with a fixed name (da_mon_this). While this works for 'static' variables (each translation unit gets its own copy), DEFINE_PER_CPU internally generates a non-static dummy variable __pcpu_unique_<n> for each per-cpu definition. The requirement for this variable to be unique although static exists for modules on specific architectures (alpha) and if the kernel is built with CONFIG_DEBUG_FORCE_WEAK_PER_CPU (e.g. Fedora's debug kernel). When multiple per-cpu monitors (e.g. sco and sts) are built-in simultaneously, they all produce the same __pcpu_unique_da_mon_this symbol, causing a link error: ld: kernel/trace/rv/monitors/sts/sts.o: multiple definition of `__pcpu_unique_da_mon_this'; kernel/trace/rv/monitors/sco/sco.o: first defined here Fix this by introducing a DA_MON_NAME macro that expands to a per-monitor unique name (da_mon_<MONITOR_NAME>) via the existing CONCATENATE helper. This restores the uniqueness that was present before the refactoring.
