Ali thanks for your valuable comments. Would you suggest me an alternative
method to implement the structure I explained?

My interpretation of what you got is as follows, based on what you've
said you'll be assigning each list_head to:

struct noop_data {
   struct list_head readQueue; // You haven't explicitly stated which
                               // LL this will be assigned to.
   struct list_head writeQueue;// The head of a LL of 'struct bundle'
                               // nodes.
    struct bundle {
     int bundleNumber;
     int size;
      struct list_head bundlesQueue; // The LL of 'struct bundle'
     struct list_head reqsQueue; // The head of a LL of
                                 // 'struct request'?
     int filled[8];
   } bun;
   unsigned int starved;
};

Depending on how you're going to assign these, you may end up with
spaghetti. As I indicated before, the nested inclusion of 'struct
bundle' is likely wrong.

later,

"noop_data" has a reference to start point of bundles list, called
"writeQueue"
"bundle" has a reference to start point of requests list, called
"reqsQueue".
"bundle" knows its related list using "bundlesQueue".
"request" knows its related list using "queuelist". (request struct is
already implemented in kernel)

struct bundle {
    int bundleNumber;
    int size;
    struct list_head bundlesQueue;
    struct list_head reqsQueue;
    int filled[8];
};

struct noop_data {
    struct list_head readQueue;
    struct list_head writeQueue;
    struct bundle bun;
    unsigned int starved;
};
