Arnd Bergmann 629d9d1caf mm: avoid uninitialized variable in tracepoint ... A newly added tracepoint in the hugepage code uses a variable in the error handling that is not initialized at that point: include/trace/events/huge_memory.h:81:230: error: 'isolated' may be used uninitialized in this function [-Werror=maybe-uninitialized] The result is relatively harmless, as the trace data will in rare cases contain incorrect data. This works around the problem by adding an explicit initialization.
