BBR patch on latest src, build failed.

[hshh]

Hi all,

I patched D21582.id62213.diff to latest head src that revision 352587,
kernel build failed.

According to previous mail, I can build the kernel successfully with
revision 352483.

OS is 13.0-CURRENT amd64.

Kernel config file,

include         GENERIC-NODEBUG
ident           hshh
makeoptions     WITH_EXTRA_TCP_STACKS=1
options         TCPHPTS
options         RATELIMIT

The error log,

--- tcp_bbr.ko.full ---
