      Pull cifs fixes from Steve French:
       "CIFS/SMB3 changes:
      
         - three fixes for stable
      
         - add fiemap support
      
         - improve zero-range support
      
         - various RDMA (smb direct fixes)
      
        I have an additional set of fixes (for improved handling of sparse
        files, mode bits, POSIX extensions) that are still being tested that
        are not included in this pull request but I expect to send in the next
        week"

        I only did some trivial tests to verify that it does not break x86,

      Ronnie Sahlberg authored
      For SMB1 oplock breaks we would grab one credit while sending the PDU
      but we would never relese the credit back since we will never receive a
      response to this from the server. Eventuallt this would lead to a hang
      once all credits are leaked.
      
      Fix this by defining a new flag CIFS_NO_SRV_RSP which indicates that there
      is no server response to this command and thus we need to add any credits back
      immediately after sending the PDU.

      cifs: fix smb3_zero_range for Azure · c425014a
      Ronnie Sahlberg authored
      For zero-range that also extend the file we were sending this as a
      compound of two different operations; a fsctl to set-zero-data for the range
      and then an additional set-info to extend the file size.
      This does not work for Azure since it does not support this fsctl which leads
      to fallocate(FALLOC_FL_ZERO_RANGE) failing but still changing the file size.
      
      To fix this we un-compound this and send these two operations as separate
      commands, firsat one command to set-zero-data for the range and it this
      was successful we proceed to send a set-info to update the file size.

      When transport is being destroyed, it's possible that some processes may
      hold memory registrations that need to be deregistred.
      
      Call them first so nobody is using transport resources, and it can be
      destroyed.

      cifs: smbd: Retry on memory registration failure · b7972092
      Long Li authored
      Memory registration failure doesn't mean this I/O has failed, it means the
      transport is hitting I/O error or needs reconnect. This error is not from
      the server.
      
      Indicate this error to upper layer, and let upper layer decide how to
      reconnect and proceed with this I/O.

      cifs: smbd: Indicate to retry on transport sending failure · 62fdf670
      Long Li authored
      Failure to send a packet doesn't mean it's a permanent failure, it can't be
      returned to user process. This I/O should be retried or failed based on
      server packet response and transport health. This logic is handled by the
      upper layer.
      
      Give this decision to upper layer.
