From 5148bf4ebc1f59dc6a0ec43a220c55ff0771246e Mon Sep 17 00:00:00 2001 From: Tom Tucker Date: Sun, 30 Dec 2007 21:07:25 -0600 Subject: svc: Add transport specific xpo_release function The svc_sock_release function releases pages allocated to a thread. For UDP this frees the receive skb. For RDMA it will post a receive WR and bump the client credit count.
