Q: can rlim_t be a long long type on linux

[Dmitry V. Levin]

Hi,

While writing a prlimit64 syscall parser I found a seemingly dead
HAVE_LONG_LONG_RLIM_T code in resource.c that implements [gs]etrlimit
parsers for systems where sizeof(rlim_t) == sizeof(long long).

Looking at "struct rlimit" and "struct compat_rlimit" definitions in
include/linux/resource.h and include/linux/compat.h I see no way for
sizeof(rlim_t) to be greater than sizeof(long) on linux.

Is it correct that rlim_t cannot be a long long type on linux,
or am I missing something?
