Merge tag 'block-6.2-2023-01-20' of git://git.kernel.dk/linux

Pull block fixes from Jens Axboe:
 "Various little tweaks all over the place:

   - NVMe pull request via Christoph:
       - fix controller shutdown regression in nvme-apple (Janne Grunau)
       - fix a polling on timeout regression in nvme-pci (Keith Busch)

   - Fix a bug in the read request side request allocation caching
     (Pavel)

   - pktcdvd was brought back after we configured a NULL return on bio
     splits, make it consistent with the others (me)

   - BFQ refcount fix (Yu)

   - Block cgroup policy activation fix (Yu)

   - Fix for an md regression introduced in the 6.2 cycle (Adrian)"

* tag 'block-6.2-2023-01-20' of git://git.kernel.dk/linux:
  nvme-pci: fix timeout request state check
  nvme-apple: only reset the controller when RTKit is running
  nvme-apple: reset controller during shutdown
  block: fix hctx checks for batch allocation
  block/rnbd-clt: fix wrong max ID in ida_alloc_max
  blk-cgroup: fix missing pd_online_fn() while activating policy
  pktcdvd: check for NULL returna fter calling bio_split_to_limits()
  block, bfq: switch 'bfqg->ref' to use atomic refcount apis
  md: fix incorrect declaration about claim_rdev in md_import_device
