Actually, it turns out that it cannot be parsed even with a C compiler:

({ const char *ret = p->buffer + p->len; static const char *access_str[]
= { "---", "--x", "w--", "w-x", "-u-", "-ux", "wu-", "wux" }; union
kvm_mmu_page_role role;

...

userspace cannot possibly know from this what "union kvm_mmu_page_role"
is.
