    The code looks correct, but I think it would be nicer to change
    hrtimer_nanosleep to take a kernel pointer and have all three
    callers (common_nsleep, sys_nanosleep and compat_sys_nanosleep)
    do the copy_to_user/put_compat_timespec in the caller.

    This would also make it possible to get rid of set_fs() in
