Description

I noticed this for LTTng 2.7 and 2.6.

After configuring the metadata channel for UST, the metadata channel is not listed when listing the session. By the way, it works for the kernel domain.

To reproduce:

lttng create my
lttng enable-channel metadata -u -s my --subbuf-size 65536
lttng list my

Tracing session my: [inactive]
Trace path: /home/user/lttng-traces/my-20160127-105230

=== Domain: UST global ===

Buffer type: per UID

From the fix of bug #855:

Fix: Don't report an error when listing a session with no channels

The LTTng sessiond daemon reports an error when the list_channel
command is invoked on a session which only has a metadata channel.

The error lies in assuming that a session which has an enabled
domains also has (user-visible) channels.

*The metadata channel should be listed in a future fix.*

Fixes #855

Looks like there was no follow-up on the listing part.
