Hmm. If I run this on my current 6.10-based system, I get:
$ make CC vdso_standalone_test_x86 CC vdso_test_getrandom vdso_test_getrandom.c:43:41: error: field ‘params’ has incomplete type 43 | struct vgetrandom_opaque_params params; | ^~~~~~
Because KHDR_INCLUDES is /usr/include instead.
Christophe, any suggestions on this one? And any idea why loongarch is hitting it, but not x86 or ppc?
