So the whole include dependency is a mess.
arch/mips/include/uapi/asm/siginfo.h defines siginfo_t structure, which
requires ./include/uapi/asm-generic/siginfo.h for definition of SI_MAX_SIZE
and others, but it can't include ./include/asm-generic/siginfo.h, because
that one contains inline function copy_siginfo, which dereferences
siginfo_t structure.
It can be solved by
- Modifying generic siginfo definition to allow swapping si_code and
si_errno either by changing the definition to
typedef struct siginfo {
int si_signo;
int __ARCH_SI_SECOND_MEMBER;
int __ARCH_SI_THIRD_MEMBER;
or by providing swapping define
typedef struct siginfo {
int si_signo;
#ifdef __ARCH_SI_SWAP_ERRNO_CODE
int si_code;
int si_errno;
#else
int si_errno;
int si_code;
#endif
then the generic definition can be used.
- Coping copy_siginfo into arch specific include file also solves the problem
- Use #ifdef __KERNEL__
Comments, please.
