Re: [PATCH bpf-next v2] samples/bpf: Set flag __SANE_USERSPACE_TYPES__ for MIPS to fix build warnings

Hello:

This patch was applied to bpf/bpf-next.git (refs/heads/master):

There exists many build warnings when make M=samples/bpf on the Loongson
platform, this issue is MIPS related, x86 compiles just fine.

Here are some warnings:
