Revert "ipv4: make net_protocol const"
This reverts commit aa8db499ea67cff1f5f049033810ffede2fe5ae4. Early demux structs can not be made const. Doing so results in: [ 84.967355] BUG: unable to handle kernel paging request at ffffffff81684b10 [ 84.969272] IP: proc_configure_early_demux+0x1e/0x3d [ 84.970544] PGD 1a0a067 [ 84.970546] P4D 1a0a067 [ 84.971212] PUD 1a0b063 [ 84.971733] PMD 80000000016001e1 [ 84.972669] Oops: 0003 [#1] SMP [ 84.973065] Modules linked in: ip6table_filter ip6_tables veth vrf [ 84.973833] CPU: 0 PID: 955 Comm: sysctl Not tainted 4.13.0-rc6+ #22 [ 84.974612] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.7.5-20140531_083030-gandalf 04/01/2014 [ 84.975855] task: ffff88003854ce00 task.stack: ffffc900005a4000 [ 84.976580] RIP: 0010:proc_configure_early_demux+0x1e/0x3d [ 84.977253] RSP: 0018:ffffc900005a7dd0 EFLAGS: 00010246 [ 84.977891] RAX: ffffffff81684b10 RBX: 0000000000000001 RCX: 0000000000000000 [ 84.978759] RDX: 0000000000000000 RSI: 0000000000000006 RDI: 0000000000000000 [ 84.979628] RBP: ffffc900005a7dd0 R08: 0000000000000000 R09: 0000000000000000 [ 84.980501] R10: 0000000000000001 R11: 0000000000000008 R12: 0000000000000001 [ 84.981373] R13: ffffffffffffffea R14: ffffffff81a9b4c0 R15: 0000000000000002 [ 84.982249] FS: 00007feb237b7700(0000) GS:ffff88003fc00000(0000) knlGS:0000000000000000 [ 84.983231] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 84.983941] CR2: ffffffff81684b10 CR3: 0000000038492000 CR4: 00000000000406f0 [ 84.984817] Call Trace: [ 84.985133] proc_tcp_early_demux+0x29/0x30 I think this is the second time such a patch has been reverted.
