:My 2 cents? Work with John to get the APIs that affect this particular
:code stable. That means discussion and perhaps that discussion will
:take some time (if this blow-up hadn't occurred the discussion
:would already be over now ;-). Once the APIs are in place, commit your
:code in a format that makes it completely optional, just like your Giant
:lock optimizations. This means that those interested in validating
:and determining the impact of your code can easily do so by flipping
:a switch. Those who would rather debug their own subsystem problems
:in a slower, but simpler, environment can do so too.

The API is intended for the stage-2 commit. The stage-1 commit
is intended to do all the 'hard stuff' in as straightforward
a manner as possible. The sysctl / option you talk about here
existed in my patch set 2 and a half weeks ago.
I really wish you people would at least read the patch and commit
message before you comment on it.
