    hostfs: pass 64-bit timestamps to/from user space · bca30265
    Arnd Bergmann authored
    The use of 'struct timespec' is deprecated in the kernel, so we
    want to avoid the conversions from/to the proper timespec64
    structure.
    
    On the user space side, we have a 'struct timespec' that is defined
    by the C library and that will be incompatible with the kernel's
    view on 32-bit architectures once they move to a 64-bit time_t,
    breaking the shared binary layout of hostfs_iattr and hostfs_stat.
    
    This changes the two structures to use a new hostfs_timespec structure
    with fixed 64-bit seconds/nanoseconds for passing the timestamps
    between hostfs_kern.c and hostfs_user.c. With a new enough user
    space side, this will allow timestamps beyond year 2038.
