I'm a bit perplexed by these trace patches
(http://userweb.kernel.org/~akpm/mmotm/broken-out/trace-code-and-documentation.patch).
Is it useful? Will it be useful? Has anyone expressed
interest/intent to use it, etc? I haven't heard much noise about it
and I'm struggling to justify merging it.
Also, it's starting to look somewhat similar to ftrace, which also
provides sort of high-bandwidth per-cpu channels into userspace for
tracing purposes.
