Description
write_log_entries() will split a log entry at the end of the log, the remainder is written to the beginning at DATA_RING_BUFFER_OFFSET. On the read side aio_read_data_block() doesn't handle this case and just crashes.
Unless the workload in use is <= 4K, the image is rendered unusable sooner or later.
