One thing about the current, system-call based interface that is kind-of
cool, and different from both what you propose and what was described
as being implemented for ARM, is that Ralf's scheme is per-thread.
I don't know if that power really outweighs the ease-of-use aspect
of being able to manipuate it from the shell command line, but it's
not something to throw away lightly. I have no issues with moving
the log data, should it be resurrected, from syslog to /sys/kernel/whatever,
though.
