  [CIFS] cifs: fix oops on mount when CONFIG_CIFS_DFS_UPCALL is enabled
  [CIFS] Fix hang in mount when negprot causes server to kill tcp session
  disable most mode changes on non-unix/non-cifsacl mounts
  [CIFS] Correct incorrect obscure open flag
  [CIFS] warn if both dynperm and cifsacl mount options specified
  silently ignore ownership changes unless unix extensions are enabled or we're faking uid changes
  [CIFS] remove trailing whitespace
  when creating new inodes, use file_mode/dir_mode exclusively on mount without unix extensions
  on non-posix shares, clear write bits in mode when ATTR_READONLY is set
  [CIFS] remove unused variables

fs/cifs/CHANGES

@@ -2,6 +2,11 @@ Version 1.53
 ------------
 DFS support added (Microsoft Distributed File System client support needed
 for referrals which enable a hierarchical name space among servers).
+Disable temporary caching of mode bits to servers which do not support
+storing of mode (e.g. Windows servers, when client mounts without cifsacl
+mount option) and add new "dynperm" mount option to enable temporary caching
+of mode (enable old behavior).  Fix hang on mount caused when server crashes
+tcp session during negotiate protocol.
 
 Version 1.52
