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)

      - 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

+The NVMe PCI endpoint function target driver allows exposing an NVMe target
 controller over a PCIe link, thus implementing an NVMe PCIe device similar to a
 regular M.2 SSD. The target controller is created in the same manner as when
 using NVMe over fabrics: the controller represents the interface to an NVMe
 subsystem using a port. The port transfer type must be configured to be
 "pci". The subsystem can be configured to have namespaces backed by regular
 files or block devices, or can use NVMe passthrough to expose to the PCI host an
