tipc: Elimination of print buffer chaining
This patch revamps TIPC's print buffer subsystem to eliminate support for arbitrary chains of print buffers, which were rarely needed and difficult to use safely. In its place, print buffers can now be configured to echo their output to the system console. This provides an equivalent for the only chaining currently utilized by TIPC, in a faster and more compact manner. Signed-off-by: Allan Stephens <allan.stephens@windriver.com> Signed-off-by: David S.
