This third bundle (3 more to come in this patch set) is largely self-contained does the following for the TFRC history * implements locking * removes unused fields (smaller footprint of structure) * simplifies to use singly-linked list (suggestion by Arnaldo) Little is added here, many lines are removed. Patch #1: Removes two fields, _sent, and _rtt, which are referenced nowhere in the code. Patch #2: Migration to singly-linked TX history -- introduction of data structures. Patch #3: Introduction of consistent naming scheme for functions and fields located in the dccp_tfrc_lib module: all such objects now start with `tfrc_' prefix. Patch #4: Allocation (constructor) and de-allocation (destructor) routines for TFRC TX history. Patch #5: Querying function to look up the send time, lock-protected against concurrent write. Patch #6: Update CCID3 TX RTT sampling to use ktime_t (Ian, this is one of the dependencies: upgrading to ktime_t could only be done after introducing the TX history; ccid3_hc_tx_update_x() is resolved subsequently. - To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
