#     Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
#     
#     Pull rdma fixes from Doug Ledford:
#      "Fairly small pull request for -rc3. I'm out of town the rest of this
#       week, so I made sure to clean out as much as possible from patchworks
#       in enough time for 0-day to chew through it (Yay! for 0-day being back
#       online! :-)). Jason might send through any emergency stuff that could
#       pop up, otherwise I'm back next week.
#     
#       The only real thing of note is the siw ABI change. Since we just
#       merged siw *this* release, there are no prior kernel releases to
#       maintain kernel ABI with. I told Bernard that if there is anything
#       else about the siw ABI he thinks he might want to change before it
#       goes set in stone, he should get it in ASAP. The siw module was around
#       for several years outside the kernel tree, and it had to be revamped
#       considerably for inclusion upstream, so we are making no attempts to
#       be backward compatible with the out of tree version. Once 5.3 is
#       actually released, we will have our baseline ABI to maintain.
#     
#       Summary:
#     
#        - Fix a memory registration release flow issue that was causing a
#          WARN_ON (mlx5)
#     
#        - If the counters for a port aren't allocated, then we can't do
#          operations on the non-existent counters (core)
#     
#        - Check the right variable for error code result (mlx5)
#     
#        - Fix a use after free issue (mlx5)
#     
#        - Fix an off by one memory leak (siw)
#     
#        - Actually return an error code on error (core)
#     
#        - Allow siw to be built on 32bit arches (siw, ABI change, but OK
#          since siw was just merged this merge window and there is no prior
#          released kernel to maintain compatibility with and we also updated
#          the rdma-core user space package to match)"
