Wang Nan 2d11c65071 perf record: Prevent reading invalid data in record__mmap_read ... When record__mmap_read() requires data more than the size of ring buffer, drop those data to avoid accessing invalid memory. This can happen when reading from overwritable ring buffer, which should be avoided. However, check this for robustness.
