From: Gerrit Renker Date: Wed, 26 Sep 2007 05:42:27 +0000 (-0700) Subject: [DCCP]: Parameter renaming X-Git-Tag: v2.6.24-rc1~1454^2~360 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b0d045ca45a44d9f8bd66d0a10558b10c60f895a;p=linux-2.6 [DCCP]: Parameter renaming The parameter `seq' of dccp_send_sync() is in fact an acknowledgement number and not a sequence number - thus renamed by this patch into `ackno'. Secondly, a `critical' warning is added when a Sync/SyncAck could not be sent. Sanity: I have checked all other functions that are called in dccp_transmit_skb, there are no clashes with the use of dccpd_ack_seq; no other function is using this slot at the same time.
