The options "sync", "async", "dirsync", "lazytime", "nolazytime", "mand" and "nomand" make no sense for the mqueue filesystem. If these options are supplied to fsconfig(FSCONFIG_SET_FLAG), then return -EINVAL instead of silently ignoring the option.
Any implementation, such as mount(8) that needs to parse this option without failing should simply ignore the return value from fsconfig().
