I'm writing a driver that provides an ethernet like interface to a WAN
link. The device DMA's the data from me, then tells me when it's
finished. At that point I free the skb. However I get the following
warning
kernel: Warning: kfree_skb on hard IRQ d092c301
What is bad about calling kfree_skb from within a hard IRQ? I'm afraid
looking at the code that spat out the error message didn't help me, and
since it's only a warning I'm assuming it's not fatal, but shouldn't be
done for some reason.
Thanks.
Bill
