      NFS: Remove nfs41_server_notify_{target|highest}_slotid_update() · 3f10a6af
      Anna Schumaker 提交于
      All these functions do is call nfs41_ping_server() without adding
      anything.  Let's remove them and give nfs41_ping_server() a better name
      instead.

      NFSv4: don't set SETATTR for O_RDONLY|O_EXCL · efcbc04e
      NeilBrown 提交于
      It is unusual to combine the open flags O_RDONLY and O_EXCL, but
      it appears that libre-office does just that.
      
      [pid  3250] stat("/home/USER/.config", {st_mode=S_IFDIR|0700, st_size=8192, ...}) = 0
      [pid  3250] open("/home/USER/.config/libreoffice/4-suse/user/extensions/buildid", O_RDONLY|O_EXCL <unfinished ...>
      
      NFSv4 takes O_EXCL as a sign that a setattr command should be sent,
      probably to reset the timestamps.
      
      When it was an O_RDONLY open, the SETATTR command does not
      identify any actual attributes to change.
      If no delegation was provided to the open, the SETATTR uses the
      all-zeros stateid and the request is accepted (at least by the
      Linux NFS server - no harm, no foul).
      
      If a read-delegation was provided, this is used in the SETATTR
      request, and a Netapp filer will justifiably claim
      NFS4ERR_BAD_STATEID, which the Linux client takes as a sign
      to retry - indefinitely.
      
      So only treat O_EXCL specially if O_CREAT was also given.
