Re: dma_skb_copy_datagram_iovec not EXPORTed

Greetings,
I am a developer of the kernel AoE (ATA over Ethernet) driver. I am
attempting to add dma offloading of data receive, following in TCP's
footsteps via config option NET_DMA. There is a function in
net/core/user_dma.c, dma_skb_copy_datagram_iovec, that appears to be
exactly what I need, but this function is not EXPORTed for use by
external modules.
Does anyone know why? Since the NET_DMA option is documented as
"Network: TCP receive copy offload" perhaps it's just an oversight
that anyone else might benefit from it?
Cheers,
Sam
Sam,
I think the general rule is not to export functions until there is an
actual user. I would put together a quick patch with your description
above to export it and send it straight to netdev@xxxxxxxxxxxxxxxx
FYI: I assume you know Jeff Garzik is the maintainer of both a lot of
network drivers and the libata implementation of ATA. He should be
monitoring netdev, and I know he is on linux-ide all the time. Also,
I think he hangs out on a IRC somewhere, but I don't know where.
