- Would you mind a patch that makes the code only use the per-CPU
buffers if we are running atomically to begin with?

That would mean dropping the first packet so no.

I think you misunderstood me: the idea is not to allocate the per-CPU
buffers at that time, but avoiding them and use the heap directly (as
my patch does now). This way, we don't unnecessarily disable
preemption for calls executing in process context.

When we actually have a user other than IPcomp then we could
try this optimisation.  Otherwise I think it'd be a waste of
time.

Cheers,
