#     Pull block fixes from Jens Axboe:
#      "Mostly just NVMe, but also a single fixup for BFQ for a regression
#       that happened during the merge window. In detail:
#     
#        - NVMe pull requests via Christoph:
#           - Fix doorbell buffer value endianness (Klaus Jensen)
#           - Fix Linux vs NVMe page size mismatch (Keith Busch)
#           - Fix a potential use memory access beyong the allocation limit
#             (Keith Busch)
#           - Fix a multipath vs blktrace NULL pointer dereference (Yanjun
#             Zhang)
#           - Fix various problems in handling the Command Supported and
#             Effects log (Christoph Hellwig)
#           - Don't allow unprivileged passthrough of commands that don't
#             transfer data but modify logical block content (Christoph
#             Hellwig)
#           - Add a features and quirks policy document (Christoph Hellwig)
#           - Fix some really nasty code that was correct but made smatch
#             complain (Sagi Grimberg)
#     
#        - Use-after-free regression in BFQ from this merge window (Yu)"
