Hi Amirali, > implemented a two-dimensioned list, using what I understood about kernel > list. But as I debugged my code, it seems that my concept is wrong.

So getting another opinion would be prudent. As for a manual, Wolfgang Mauerer's book, Professional Linux Kernel Architecture, is an excellent resource. It does touch on double linked-lists (LL), though I've only glanced at it. > "noop_data" has a reference to start point of bundles list, called > "writeQueue" I don't think so. See below. > struct bundle { > struct list_head bundlesQueue; > struct list_head reqsQueue; What I see here is that you are putting such nodes on 2 LLs. > struct noop_data { > struct list_head readQueue; > struct list_head writeQueue; What I see here is that you are putting such nodes on 2 LLs, but > struct bundle bun; each node has a single node of the type 'struct bundle' ie a struct which has int bundleNumber; int size; ... int filled[8]; Likely, this is not what you want. later, ali _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
