[lttng-dev] lttng-tools lttng-ctl.c lttng_channel_set_default_attr does not have per-UID as its default

   Since the 8692d4e lttng-tools commit (12 July), the default configuration for user-space channels is per-UID (it would be nice if 'lttng enable-channel --help' said so, by the way).  However, in lttng-tools\src\lib\lttng-ctl\lttng-ctl.c, one can still read:

void lttng_channel_set_default_attr(struct lttng_domain *domain,
		struct lttng_channel_attr *attr)
{
[...]
	switch (domain->type) {
	case LTTNG_DOMAIN_KERNEL:
	 	 [...]
		break;
	case LTTNG_DOMAIN_UST:
		switch (domain->buf_type) {
		case LTTNG_BUFFER_PER_UID:
			[...]
			break;
		case LTTNG_BUFFER_PER_PID:
		default:
			[...]
			break;
		}
	default:
		/* Default behavior: leave set to 0. */
		break;
	}
}

   Surely the LTTNG_BUFFER_PER_UID  and LTTNG_BUFFER_PER_PID case blocks should be switched around?
