[PATCH] block: __elv_next_request() shouldn't call into the elevator if bypassing

2014-01-29 Thread Tejun Heo
request_queue bypassing is used to suppress higher-level function of a request_queue so that they can be switched, reconfigured and shut down. A request_queue does the followings while bypassing. * bypasses elevator and io_cq association and queues requests directly to the FIFO dispatch queue.
