2.6.3-mm4-rcu_ll SMP memory leak ?

From: Peter Zijlstra

Hi,


I'm running said kernel, and after 5 days I've noticed that all my
memory is gone. Even if I quit every possible application there is
still 600MB+ gone, not in buffers/cache but just used, and no app to
show for it.

I append my current uname,top and lsmod output (while writing this mail)
and as one can see I'm lucky if the RES column adds up to 150m.

is there some way to see how much memory the kernel uses for its
internal structures and then maybe pinpoint the leak?

Kind regards,

Peter Zijlstra
