      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.
