[PATCH V3 2/7] blk-flush: don't run queue for requests of bypassing flush

From: Ming Lei
Date: Thu Nov 02 2017 - 11:25:22 EST


blk_insert_flush() should only insert request since run queue always
follows it.

In case of bypassing flush, we don't need to run queue because every
blk_insert_flush() follows one run queue.
