Now that most archs have __NR_memfd_create, this is:

Hmm. I am seeing failures on x86_64 on top of Linus's tree
(without this patch)
make -C tools/testing/selftests/memfd/make: Entering directory
`/lkml/linus_git_3.14/tools/testing/selftests/memfd'
gcc -D_FILE_OFFSET_BITS=64
-I../../../../arch/x86/include/generated/uapi/
-I../../../../arch/x86/include/uapi/ -I../../../../include/uapi/
-I../../../../include/ memfd_test.c -o memfd_test
memfd_test.c: In function ‘sys_memfd_create’:
memfd_test.c:26:17: error: ‘__NR_memfd_create’ undeclared (first use in
this function)
return syscall(__NR_memfd_create, name, flags);
^
memfd_test.c:26:17: note: each undeclared identifier is reported only
once for each function it appears in
Could you please look into this?? It appears __NR_memfd_create isn't
defined on x86_64???
thanks,

Hi Shuah,
Did you compile the tree before trying to compile this test? Compiling
the kernel will generate the required symbols which are used in this
test.
Thanks!

You need the headers installed in your system. By dropping the
arch-includes from the Makefile, we require 3.17 headers in
/usr/include.

Sorry - wrong system without the headers installed. My bad.
