Subject: [PATCH] getrlimit03: adjust a bit of code to compatiable with mips32
Error info:
getrlimit03.c:104: FAIL: __NR_prlimit64(0) had rlim_cur =
ffffffffffffffff but __NR_getrlimit(0) had rlim_cur = 7fffffff
According to kernel code: [arch/mips/include/uapi/asm/resource.h]
RLIM_INFINITY is set to 0x7fffffffUL instead of ULONG_MAX on mips32.
/*
* SuS says limits have to be unsigned.
* Which makes a ton more sense anyway,
* but we keep the old value on MIPS32,
* for compatibility:
*/
#ifndef __mips64
# define RLIM_INFINITY 0x7fffffffUL
#endif
Adding conditional statement about mips to fix this.
