From 41179e2de6962b46d1d9f2b4437243ac740efdec Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Tue, 17 Jul 2007 18:37:42 -0700 Subject: [PATCH] IB/iser: Make a couple of functions static Make iser_conn_release() and iser_start_rdma_unaligned_sg() static, since they are only used in the .c file where they are defined. In addition to being a cleanup, this even shrinks the generated code by allowing the single call of iser_start_rdma_unaligned_sg() to be inlined into its callsite.
