work in the latest mainline kernel.
Since it is very simple and useful for newbies, I think it is
necessary to be upstreamed.

Here are some errors:

So we can do the similar things in samples
just add
platform specific and generic include dir for MIPS Loongson64 to
fix the build errors.

With #ifndef __SANE_USERSPACE_TYPES__ in tools/include/linux/types.h,
the above error has gone and this ifndef change does not hurt other

I do not think this fix is correct. x86 does not define its own
rwonce.h and still compiles fine.
As noted in the above, we have include/asm-generic/rwonce.h.
Once you do a proper build, you will have rwonce.h in arch
generated directory like
-bash-4
o be feasible, so we should
update it to reflect the reality.

There exists many build errors and warnings when make M=samples/bpf,
this patch series fix some of them, I will submit some other patches
related with MIPS later.
Tiezhu Yang (2):
samples/bpf: Set flag __SANE_USERSPACE_TYPES__ for MIPS to fix build
warnings
compiler.h: Include asm
Hi all,
I found the following build errors and warnings when make M=samples/bpf
on the Loongson 3A3000 platform which belongs to MIPS arch.
Are theseknown issues? Should I submit patches to fix them? (1) fatal error:

When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.
