4.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: Tang Junhui <[email protected]> commit 502b291568fc7faf1ebdb2c2590f12851db0ff76 upstream. Missed reading IOs are identified by s->cache_missed, not the s->cache_miss, so in trace_bcache_read() using trace_bcache_read to identify whether the IO is missed or not.
