       - EXPORT_SYMBOL for asm source by Al Viro.
      
         This does bring a regression, because genksyms no longer generates
         checksums for these symbols (CONFIG_MODVERSIONS). Nick Piggin is
         working on a patch to fix this.
      
         Plus, we are talking about functions like strcpy(), which rarely
         change prototypes.

      Pull rdma qedr RoCE driver from Doug Ledford:
       "Early on in the merge window I mentioned I had a backlog of new
        drivers waiting to be reviewed and that, in addition to the hns-roce
        driver, I wanted to get possible a couple more reviewed. I ended up
        only having the time to complete one of the additional drivers.
      
        During Dave Miller's pull request this go around, there were a series
        of 9 patches to the QLogic qed net driver that add basic support for a
        paired RoCE driver. That support is currently not functional because
        it is missing the matching RoCE driver in the RDMA subsystem. I
        managed to finish that review. However, because it goes against part
        of Dave's net pull, and a part that was accepted a day or two after
        the merge window opened, to apply cleanly it has to be applied to
        either the tip of Dave's net branch, or as I did in this case, I just
        applied it to your master after you had taken Dave's pull request."

       "This merge window was the first where Huawei had to try and coordinate
        their patches between their net driver and their new roce driver
        (similar to mlx4 and mlx5).
      
        They didn't do horribly, but there were some issues (and we knew that
        because they simply didn't know what to do in the beginning). As a
        result, I had a set of patches that depended on some patches that
        normally would have come to you via Dave's tree. Those patches have
        been on netdev@ for a while, so I got Dave to give me his approval to
        send them to you. As such, the other 29 patches I had behind them are
        also now ready to go.
      
        This catches the hns and hns-roce drivers up to current, and for
        future patches we are working with them to get them up to speed on how
        to do joint driver development so that they don't have these sorts of
        cross tree dependency issues again. BTW, Dave gave me permission to
        add his Acked-by: to the patches against the net tree, but I've had
        this branch through 0day (but not linux-next since it was off by
        itself) and I didn't want to rebase the series just to add Dave's ack
        for the 8 patches in the net area.
      
        Updates to the hns drivers:
      
         - Small patch set for hns net driver that the roce patches depend on
      
         - Various fixes to the hns-roce driver
      
         - Add connection manager support to the hns-roce driver"

      This helper is for filesystems that want to read the symlink and are better

      readlink() interface (copy into a userspace buffer).
      
      Also call the LSM hook for readlink (not get_link) since this is for
      symlink reading not following.

      Pull nfsd updates from Bruce Fields:
       "Some RDMA work and some good bugfixes, and two new features that could
        benefit from user testing:
      
         - Anna Schumacker contributed a simple NFSv4.2 COPY implementation.
           COPY is already supported on the client side, so a call to
           copy_file_range() on a recent client should now result in a
           server-side copy that doesn't require all the data to make a round
           trip to the client and back.
      
         - Jeff Layton implemented callbacks to notify clients when contended
           locks become available, which should reduce latency on workloads
           with contended locks"
