Rusty! As you might know we are working on cleaning up the licensing mess in the kernel and convert it to SPDX license identifiers as the only source of license information. Archaeology found the following unspecific GPL license references, which have been authored by you: kernel/cpu.c: * This code is licenced under the GPL. include/linux/netfilter_ipv4.h: * (C)1998 Rusty Russell -- This code is GPL. include/linux/netfilter_ipv6.h: * (C)1998 Rusty Russell -- This code is GPL. net/ipv4/netfilter.c: * Rusty Russell (C) 2000 -- This code is GPL. net/ipv6/netfilter.c: * Rusty Russell (C) 2000 -- This code is GPL. net/netfilter/nf_queue.c: * Rusty Russell (C)2000 -- This code is GPL. net/netfilter/core.c: * This code is GPL. net/netfilter/core.c lost your (C) with b3a61254d83d5. scripts/mod/modpost.c scripts/mod/file2alias.c: * This software may be used and distributed according to the terms * of the GNU General Public License, incorporated herein by reference. include/uapi/linux/netfilter_arp.h: * (C)2002 Rusty Russell IBM -- This code is GPL. include/uapi/linux/netfilter_decnet.h: * (C)1998 Rusty Russell -- This code is GPL. include/uapi/linux/netfilter_ipv4.h: * (C)1998 Rusty Russell -- This code is GPL. include/uapi/linux/netfilter_ipv6.h: * (C)1998 Rusty Russell -- This code is GPL. Can you please either send cleanup patches for the affected files or indicate which GPLv2 variant you had in mind and I run it through my cleanup machinery. The files in 'include/uapi/' have already SPDX license tags, but it would be nice to remove the 'This code is GPL.' blurb for clarity. Thanks, Thomas
