This new function enables ring-buffer\nbuffer_data_read_page users to not call the racy\nring_buffer_subbuf_size_get(). This makes the spare_size member of\nftrace_buffer_info redundant.\n\nFinally, handle buffer_data_read_page/reader_page order discrepancy in\nring_buffer_read_page(). On a mismatch simply copy manually the data to\nthe buffer_data_read_page."
