Here's a better question: does *anything* use ->current_ring_status at all? Answer: no. Next question: did anything use it in the past? git log -p drivers/net/tokenging/smctr.c in historical trees shows that it had always been defined that way and that it had never been used at all. So how about removing the damn field completely? Or asking the driver's author what the hell had it been about? -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
