[pulseaudio-discuss] [PATCH] sink: Prevent filter sink cycles

[David Henningsson]

While looking at bug 44397,

https://bugs.freedesktop.org/show_bug.cgi?id=44397

Gnome's volume control somehow wanted to create a filter sink cycle. I'm 
attaching a patch to prevent this, which seems to have worked  (at least 
there is no crash!), but before I push it:

Is there any reason, any use case, where we actually would want a cycle? 
I can't think of any, but just wanted another thought in case I missed 
anything.
