Kernel buffering scheme

[PSRCode]

It was brought to my attention that the following might confuse certain user as to if multiple channels with their own set of buffers can be created on a system for the kernel domain.

The Linux kernel tracing domain has only one available buffering scheme which is
to allocate a single set of ring buffers for the whole system. This scheme is similar
to the per-user option, but with a single, global user “running” the kernel.

Seems like the following might be the confusing part a single set of ring buffers for the whole system.

Users could be tempted to conclude that a single kernel domain can be created.

I do not have a change proposition to be honest. Might be a good idea to put an emphasis such as "for a given channel".
