Pull block updates from Jens Axboe:

 - NVMe pull requests via Keith:
      - Target support for PCI-Endpoint transport (Damien)
      - TCP IO queue spreading fixes (Sagi, Chaitanya)
      - Target handling for "limited retry" flags (Guixen)
      - Poll type fix (Yongsoo)
      - Xarray storage error handling (Keisuke)
      - Host memory buffer free size fix on error (Francis)

 - MD pull requests via Song:
      - Reintroduce md-linear (Yu Kuai)
      - md-bitmap refactor and fix (Yu Kuai)
      - Replace kmap_atomic with kmap_local_page (David Reaver)

 - Quite a few queue freeze and debugfs deadlock fixes

   Ming introduced lockdep support for this in the 6.13 kernel, and it
   has (unsurprisingly) uncovered quite a few issues

 - Use const attributes for IO schedulers

 - Remove bio ioprio wrappers

 - Fixes for stacked device atomic write support

 - Refactor queue affinity helpers, in preparation for better supporting
   isolated CPUs

 - Cleanups of loop O_DIRECT handling

 - Cleanup of BLK_MQ_F_* flags

 - Add rotational support for null_blk

 - Various fixes and cleanups
