  [CIFS] fix some settings of cifsAttrs after calling SetFileInfo and SetPathInfo
  cifs: explicitly revoke SPNEGO key after session setup
  cifs: Convert cifs to new aops.
  [CIFS] update DOS attributes in cifsInode if we successfully changed them
  cifs: remove NULL termination from rename target in CIFSSMBRenameOpenFIle
  cifs: work around samba returning -ENOENT on SetFileDisposition call
  cifs: fix inverted NULL check after kmalloc
  [CIFS] clean up upcall handling for dns_resolver keys
  [CIFS]  fix busy-file renames and refactor cifs_rename logic
  cifs: add function to set file disposition
  [CIFS] add constants for string lengths of keynames in SPNEGO upcall string
  cifs: move rename and delete-on-close logic into helper function
  cifs: have find_writeable_file prefer filehandles opened by same task
  cifs: don't use GFP_KERNEL with GFP_NOFS
