From 1fd40b5ea72cf830cfb932bbf791533931c615e9 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Tue, 30 Jun 2020 18:25:00 +0800 Subject: blk-mq: pass obtained budget count to blk_mq_dispatch_rq_list Pass obtained budget count to blk_mq_dispatch_rq_list(), and prepare for supporting fully batching submission. With the obtained budget count, it is easier to put extra budgets in case of .queue_rq failure. Meantime remove the old 'got_budget' parameter.
