    plist: Shrink struct plist_head · bf6a9b83
    Lai Jiangshan authored
    struct plist_head is used in struct task_struct as well as struct
    rtmutex. If we can make it smaller, it will also make these structures
    smaller as well.
    The field prio_list in struct plist_head is seldom used and we can get
    its information from the plist_nodes. Removing this field will decrease
    the size of plist_head by half.
