Perhaps this is confusing cifs. Can you check where all of the files in your case share that property? example: [avi@firebolt linux-2.6]$ find net -iname ipt_tos.c net/ipv4/netfilter/ipt_TOS.c net/ipv4/netfilter/ipt_tos.c [avi@firebolt linux-2.6]$ find net -iname ipt_ecn.c net/ipv4/netfilter/ipt_ECN.c net/ipv4/netfilter/ipt_ecn.c -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
