From 276f2edc52e309b38a216245952e05880e182c83 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 28 Nov 2007 11:15:40 -0200 Subject: [TFRC]: Migrate TX history to singly-linked lis This patch was based on another made by Gerrit Renker, his changelog was: ------------------------------------------------------ The patch set migrates TFRC TX history to a singly-linked list. The details are: * use of a consistent naming scheme (all TFRC functions now begin with `tfrc_'); * allocation and cleanup are taken care of internally; * provision of a lookup function, which is used by the CCID TX infrastructure to determine the time a packet was sent (in turn used for RTT sampling); * integration of the new interface with the present use in CCID3. ------------------------------------------------------ Simplifications I did: . removing the tfrc_tx_hist_head that had a pointer to the list head and another for the slabcache. . No need for creating a slabcache for each CCID that wants to use the TFRC tx history routines, create a single slabcache when the dccp_tfrc_lib module init routine is called.
