From: Tanner Love <tannerlove@xxxxxxxxxx> 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.
