From b3d56fab333bbb3ac7300843d69e52d7bd8a016b Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Fri, 8 Mar 2013 18:51:03 -0600 Subject: [PATCH] libceph: kill args in read_partial_message_bio() There is only one caller for read_partial_message_bio(), and it always passes &msg->bio_iter and &bio_seg as the second and third arguments. Furthermore, the message in question is always the connection's in_msg, and we can get that inside the called function. So drop those two parameters and use their derived equivalents.
