From e2b3fa5af70c1e646270f6c7c799414f5e904d7a Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Tue, 20 Nov 2018 10:52:34 +0900 Subject: block: Remove bio->bi_ioc bio->bi_ioc is never set so always NULL. Remove references to it in bio_disassociate_task() and in rq_ioc() and delete this field from struct bio. With this change, rq_ioc() always returns current->io_context without the need for a bio argument. Further simplify the code and make it more readable by also removing this helper, which also allows to simplify blk_mq_sched_assign_ioc() by removing its bio argument.
