    Subject[PATCH 08/16] tools headers uapi: Sync linux/in.h copy from the kernel sources
    Date
    From: Arnaldo Carvalho de Melo <acme@redhat.com>

    To get the changes in this cset:

    65cab850f0ee ("net: Allow class-e address assignment via ifconfig ioctl")

    The macros changed in this cset are not used in tools/, so this is just
    to silence this perf tools build warning:

    Warning: Kernel ABI header at 'tools/include/uapi/linux/in.h' differs from latest version at 'include/uapi/linux/in.h'
    diff -u tools/include/uapi/linux/in.h include/uapi/linux/in.h
