Yes, right, we have always utf8 support compiled-in. Second part of that warning message should be dropped. > > if (!v || !*v) > > val = true; > > else if (!simple_getbool(v, &val))

Ok, this is truth after patch 15/18. So info about compiled module should be dropped in patch 15/18, not in this one. > > > if (!v || !*v) > > > val = true; > > > else if (!simple_getbool(v, &val))

Other fs drivers are using iocharset= mount option for specifying charset. So mark iocharset= mount option as preferred and deprecate nls= mount option.
