Hi Arnd and Peter Anvin, Other than 64-bit time_t, clock_t and suseconds_t, can you confirm that we don't need to have 64 bit off_t? See detail in link below. I can submit the patches for 64-bit time changes (include/asm-generic/posix_types.h and other archs) if everyone is agreed on this. Excerpt from https://lkml.org/lkml/2012/11/14/358 : "Obviously, we want to use 64-bit off_t, but this is achieved already through loff_t, which is used in all places in the asm-generic ABI anyway (the syscalls using off_t are stripped out). I don't think we want to have the other ones set to 64 bit on ARC or Meta, although I'm not 100% sure about ino_t and nlink_t. " Thanks. Regards Ley Foon On Mon, Apr 21, 2014 at 1:31 PM, H.
