[lttng-dev] Channel buffer allocation

[Nalin Pai]

Hi,

In the per-pid buffer scheme, when are the ring buffers allocated for each
pid? Is it when a channel is created or is it an event provided by that
process is enabled for a specific channel.

I am trying to understand whether there is an overhead to creating many
channels. Will a process incur the allocation of buffers for a channel that
is not interested in any of the events that the process is providing?
