[GIT,PULL] Core block changes for 5.9-rc1

Hi Linus, Here are the core block changes queued up for this merge window. Good amount of cleanups and tech debt removals in here, and as a result, the diffstat shows a nice net reduction in code. Changes: - Softirq completion cleanups (Christoph) - Stop using ->queuedata (Christoph) - Cleanup bd claiming (Christoph) - Use check_events, moving away from the legacy media change (Christoph) - Use inode i_blkbits consistently (Christoph) - Remove old unused writeback congestion bits (Christoph) - Cleanup/unify submission path (Christoph) - Use bio_uninit consistently, instead of bio_disassociate_blkg (Christoph) - sbitmap cleared bits handling (John) - Request merging blktrace event addition (Jan) - sysfs add/remove race fixes (Luis) - blk-mq tag fixes/optimizations (Ming) - Duplicate words in comments (Randy) - Flush deferral cleanup (Yufen) - IO context locking/retry fixes (John) - struct_size() usage (Gustavo) - blk-iocost fixes (Chengming) - blk-cgroup IO stats fixes (Boris) - Various little fixes Please pull! The following changes since commit 48778464bb7d346b47157d21ffde2af6b2d39110: Linux 5.8-rc2 (2020-06-21 15:45:29 -0700) are available in the Git repository at: git://git.kernel.dk/linux-block.git
