    /*
    * the semaphore definition
    */
    struct rw_semaphore {
    /* XXX this should be able to be an atomic_t -- paulus */
    signed int count;
    #define RWSEM_UNLOCKED_VALUE 0x00000000
    #define RWSEM_ACTIVE_BIAS 0x00000001
    #define RWSEM_ACTIVE_MASK 0x0000ffff

    that counter is split in 2 16 bit entities....
