xlator.c option validation should check for empty valid options list (for strings).
'if (!opt->value)' always fails as 'value' member is an array of size ZR_OPTION_MAX_ARRAY_SIZE and is always non-null. it should have been 'if (opt->value[0] == NULL)' instead. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
