From 85dcb1f78039cc55ccddd9622657a338b718aafe Mon Sep 17 00:00:00 2001 From: Gerrit Renker Date: Sun, 10 Dec 2006 00:24:11 -0200 Subject: [DCCP] ccid3: Reorder packet history header file No code change at all. To make the header file easier to read, the following ordering is established among the declarations: * hist_new * hist_delete * hist_entry_new * hist_head * hist_find_entry * hist_add_entry * hist_entry_delete * hist_purge Signed-off-by: Gerrit Renker Acked-by: Ian McDonald Signed-off-by: Arnaldo Carvalho de Melo --- net/dccp/ccids/lib/packet_history.h | 127 +++++++++++++++++++----------------- 1 file changed, 67 insertions(+), 60 deletions(-) (limited to 'net') diff --git a/net/dccp/ccids/lib/packet_history.h b/net/dccp/ccids/lib/packet_history.h index 4198185c6d40..1f960c19ea1b 100644 --- a/net/dccp/ccids/lib/packet_history.h +++ b/net/dccp/ccids/lib/packet_history.h @@ -49,6 +49,9 @@ #define TFRC_WIN_COUNT_PER_RTT 4 #define TFRC_WIN_COUNT_LIMIT 16 +/* + * Transmitter History data structures and declarations + */ struct dccp_tx_hist_entry { struct list_head dccphtx_node;
