      cifs: change DOS/NT/POSIX mapping of ERRnoresource · 4f2b86ab
      Jeff Layton authored
      ERRnoresource is an ERRSRV level (aka server-side) error and means "No
      resources currently available for request". Currently that maps to POSIX
      -ENOBUFS. No NT errors map to it currently.
      
      NT_STATUS_INSUFFICIENT_RESOURCES and NT_STATUS_INSUFF_SERVER_RESOURCES
      are also similar in meaning. Currently the client maps those to
      ERRnomem, which maps to -ENOMEM in POSIX.
      
      All of these mappings seem to be quite wrong to me and are confusing for
      users. All of the above errors indicate problems on the server, not the
      client. Reporting -ENOMEM or -ENOBUFS implies that the client is running
      out of resources.
      
      This patch changes those mappings. The NT_* errors are changed to map to
      the SRV level ERRnoresource. That error is in turn changed to return
      -EREMOTEIO which is the only POSIX error I could find that conveys that
      something went wrong on the server. While we're at it, change the SMB2
      equivalent error to return the same.
