[lustre-devel] [PATCH 3/3] staging: lustre: lnet/selftest: don't ignore status from lstcon_test_add

> If lstcon_test_add sets 'ret' (passed by reference) to 1,
> then lst_test_add_ioctl() ignores the return value.
> This isn't justified - the return value must be zero for 'ret'
> to be meaningful.
