[PATCH net-next,v2,0/2] net: update netdev_rx_csum_fault() print dump only once

[Tanner Love <tannerlove.kernel@gmail.com>]

From: Tanner Love <tannerlove@google.com>

First patch implements DO_ONCE_LITE to abstract uses of the ".data.once"
trick. It is defined in its own, new header file  -- rather than
alongside the existing DO_ONCE in include/linux/once.h -- because
include/linux/once.h includes include/linux/jump_label.h, and this
causes the build to break for some architectures if
include/linux/once.h is included in include/linux/printk.h or
include/asm-generic/bug.h.

Second patch uses DO_ONCE_LITE in netdev_rx_csum_fault to print dump
only once.

This is a v2 of https://patchwork.kernel.org/project/netdevbpf/patch/20210422194738.2175542-2-tannerlove.kernel@gmail.com/
