Merge tag 'for-6.17/block-20250728' of git://git.kernel.dk/linux

Pull block updates from Jens Axboe:

 - MD pull request via Yu:
      - call del_gendisk synchronously (Xiao)
      - cleanup unused variable (John)
      - cleanup workqueue flags (Ryo)
      - fix faulty rdev can't be removed during resync (Qixing)

 - NVMe pull request via Christoph:
      - try PCIe function level reset on init failure (Keith Busch)
      - log TLS handshake failures at error level (Maurizio Lombardi)
      - pci-epf: do not complete commands twice if nvmet_req_init()
        fails (Rick Wertenbroek)
      - misc cleanups (Alok Tiwari)

 - Removal of the pktcdvd driver

   This has been more than a decade coming at this point, and some
   recently revealed breakages that had it causing issues even for cases
   where it isn't required made me re-pull the trigger on this one. It's
   known broken and nobody has stepped up to maintain the code

 - Series for ublk supporting batch commands, enabling the use of
   multishot where appropriate

 - Speed up ublk exit handling

 - Fix for the two-stage elevator fixing which could leak data

 - Convert NVMe to use the new IOVA based API

 - Increase default max transfer size to something more reasonable

 - Series fixing write operations on zoned DM devices

 - Add tracepoints for zoned block device operations

 - Prep series working towards improving blk-mq queue management in the
   presence of isolated CPUs

 - Don't allow updating of the block size of a loop device that is
   currently under exclusively ownership/open

 - Set chunk sectors from stacked device stripe size and use it for the
   atomic write size limit

 - Switch to folios in bcache read_super()

 - Fix for CD-ROM MRW exit flush handling

 - Various tweaks, fixes, and cleanups
