The next is a port of the Unified tracer buffer to linux-tip and some updates.
After that is the ftrace port to use the ring buffer, followed by some
more enhancements to ftrace because of the new variable length
buffer.
I tried a few configurations and tried to test all the different ftrace
tracers, but I'm sure there may be some bugs still to work out. I worked
out all those that I found.
But, with the ring_buffer I can envision several ways to clean up
ftrace and to make adding new tracers cleaner.
I'm also thinking about making a way that each tracer can allocate
its own buffer, and allow for more than one tracer to be running
at the same time! (only with different buffers).
