Maybe use callout_reset_curcpu() to take advantage of callout's SMP
capabilities ?
Yes, that's fine. But what's the benefit of it? I don't really care whether
the callout is run on the current CPU or not. Is callout_reset_curcpu
cheaper than callout_reset?
Hi,
It is maybe not cheaper, but it will distribute the load of the
xn_alloc_rx_buffers_callout() callback, to the current CPU calling
callout_reset_curcpu(). Else xn_alloc_rx_buffers_callout() will always
be called from callback thread zero.
