Subject: linux-next: build failure after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (sparc64
defconfig) failed like this:

net/socket.o: In function `tun_xdp_to_ptr':
(.text+0x3180): multiple definition of `tun_xdp_to_ptr'
fs/compat_ioctl.o:compat_ioctl.c:(.text+0x0): first defined here
net/socket.o: In function `tun_ptr_to_xdp':
(.text+0x31a0): multiple definition of `tun_ptr_to_xdp'
fs/compat_ioctl.o:compat_ioctl.c:(.text+0x20): first defined here

Caused by commit

  fc72d1d54dd9 ("tuntap: XDP transmission")

I applied the following fix for today:
