- Relax disk zoned reporting restrictions (Niklas)
- Bio error handling zoned leak fix (Pavel)
- Start of proper add_disk() error handling (Luis, Christoph)
- blk crypto fix (Eric)
- Non-standard GPT location support (Dmitry)
- IO priority improvements and cleanups (Damien)o
- blk-throtl improvements (Chunguang)
- diskstats_show() stack reduction (Abd-Alrhman)
- Loop scheduler selection (Bart)
- Switch block layer to use kmap_local_page() (Christoph)
- Remove obsolete disk_name helper (Christoph)
- block_device refcounting improvements (Christoph)
- Ensure gendisk always has a request queue reference (Christoph)
- Misc fixes/cleanups (Shaokun, Oliver, Guoqing)"
