From d4c3cca941b64a938eaa9734585a93547c6be323 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 13 Dec 2006 00:34:04 -0800 Subject: [PATCH] constify pipe_buf_operations - pipe/splice should use const pipe_buf_operations and file_operations - struct pipe_inode_info has an unused field "start" : get rid of it.
