From 9bdb4833dd399cbff82cc20893f52bdec66a9eca Mon Sep 17 00:00:00 2001 From: John Garry Date: Wed, 6 Jul 2022 20:03:51 +0800 Subject: blk-mq: Drop blk_mq_ops.timeout 'reserved' arg With new API blk_mq_is_reserved_rq() we can tell if a request is from the reserved pool, so stop passing 'reserved' arg. There is actually only a single user of that arg for all the callback implementations, which can use blk_mq_is_reserved_rq() instead. This will also allow us to stop passing the same 'reserved' around the blk-mq iter functions next.
