Yes - there is a soft mount option for cifs.  It sets the value for
      tcon->retry
Not everywhere in the code (mostly fs/cifs/cifssmb.c probably, but perhaps
fs/cifs/transport.c should check it to) probably checks it that should
check it.

Anyone want to do some experiments and see whether we need to fix up the
code for any particular operations to retry consistent with the hard vs.
soft cifs mount option?
