#     Merge tag 'io_uring-20190323' of git://git.kernel.dk/linux-block
#     
#     Pull io_uring fixes and improvements from Jens Axboe:
#      "The first five in this series are heavily inspired by the work Al did
#       on the aio side to fix the races there.
#     
#       The last two re-introduce a feature that was in io_uring before it got
#       merged, but which I pulled since we didn't have a good way to have
#       BVEC iters that already have a stable reference. These aren't
#       necessarily related to block, it's just how io_uring pins fixed
#       buffers"
#
