error when make liburing2.6

[970315420]

When I make liburing2.6 ,the error occurs as below
In file included from send-zerocopy.c:15: /usr/include/linux/ipv6.h:19:8: error: redefinition of ‘struct in6_pktinfo’ 19 | struct in6_pktinfo { | ^~~~~~~~~~~ In file included from /usr/include/arpa/inet.h:22, from send-zerocopy.c:13: /usr/include/netinet/in.h:538:8: note: originally defined here 538 | struct in6_pktinfo | ^~~~~~~~~~~ /usr/include/linux/ipv6.h:24:8: error: redefinition of ‘struct ip6_mtuinfo’ 24 | struct ip6_mtuinfo { | ^~~~~~~~~~~ /usr/include/netinet/in.h:545:8: note: originally defined here 545 | struct ip6_mtuinfo | ^~~~~~~~~~~ make[1]: *** [send-zerocopy.t] Error 1
Why does this happen?
ps:
kernel version 5.1
gcc version 12

This is fixed in the current tree, for a while.
