Pull more block updates from Jens Axboe:

 - Improve blk-integrity segment counting and merging (Keith)

 - NVMe pull request via Keith:
      - Multipath fixes (Hannes)
      - Sysfs attribute list NULL terminate fix (Shin'ichiro)
      - Remove problematic read-back (Keith)

 - Fix for a regression with the IO scheduler switching freezing from
   6.11 (Damien)

 - Use a raw spinlock for sbitmap, as it may get called from preempt
   disabled context (Ming)

 - Cleanup for bd_claiming waiting, using var_waitqueue() rather than
   the bit waitqueues, as that more accurately describes that it does
   (Neil)

 - Various cleanups (Kanchan, Qiu-ji, David)
