Pull block fixes from Jens Axboe: - Always initialize DMA state, fixing a potentially nasty issue on the block side - btrfs zoned write fix with cached zone reports - Fix corruption issues in bcache with chained bio's, and further make it clear that the chained IO handler is simply a marker, it's not code meant to be executed - Kill old code dealing with synchronous IO polling in the block layer, that has been dead for a long time. Only async polling is supported these days - Fix a lockdep issue in tag_set management, moving it to RCU - Fix an issue with ublks bio_vec iteration - Don't unconditionally enforce blocking issue of ublk control commands, allow some of them with non-blocking issue as they do not block * tag 'block-6.19-20251211' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: blk-mq-dma: always initialize dma state blk-mq: delete task running check in blk_hctx_poll() block: fix cached zone reports on devices with native zone append block: Use RCU in blk_mq_[un]quiesce_tagset() instead of set->tag_list_lock ublk: don't mutate struct bio_vec in iteration block: prohibit calls to bio_chain_endio bcache: fix improper use of bi_end_io ublk: allow non-blocking ctrl cmds in IO_URING_F_NONBLOCK issue
