Analyze and fix the following issue in the Linux kernel code: tracing: Free buffers when a used dynamic event is removed
Problem Details: After 65536 dynamic events have been added and removed, the "type" field of the event then uses the first type number that is available (not currently used by other events). A type number is the identifier of the binary blobs in the tracing ring buffer (known as events) to map them to logic that can pa...
