Well, for old static binaries, the old syscall ABI would still have to use 32-bit off_t's and time_t's. And for dynamically linked binaries, glibc could deal with the compatibility issues with the old ABI, across the shared library interface, right? - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
