I'm not sure I fully get it yet. So with this change, we avoid using syscall numbers like __NR_ftruncate64 in favour of __NR_ftruncate. Why? (maybe there's a valid reason, just not getting it). Either way, ILP32 would still end up calling sys_ftruncate64() (rather than the native sys_ftruncate()). -- Catalin -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
