LTT Next Generation Roadmap

-(3) Find a way to make logging know when it causes a minor page fault -recursively (without ignoring silently all nested events).
-(3) Have various subbuffer sizes for high and low rate channels.

-(4) instrument kernel bottom half irqsave, spinlocks, rwlocks, seqlocks, semaphores, mutexes, brlock.
-(4) In flight recorder mode, have the low traffic channels saved as normal -tracefiles and high traffic channels being flight recorder.
-(4) Try to use my own non LOCK prefixed version of atomic operations : we are -using per-CPU variables, so it should make it possible.

(5) Support CPUs with scalable frequency.
