From c1e8d35ef5ffb393b94a192034b5e3541e005d75 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Mon, 7 Mar 2011 16:43:21 +0800 Subject: ocfs2: Remove EXIT from masklog. mlog_exit is used to record the exit status of a function. But because it is added in so many functions, if we enable it, the system logs get filled up quickly and cause too much I/O. So actually no one can open it for a production system or even for a test. This patch just try to remove it or change it. So: 1. if all the error paths already use mlog_errno, it is just removed. Otherwise, it will be replaced by mlog_errno. 2. if it is used to print some return value, it is replaced with mlog(0,...). mlog_exit_ptr is changed to mlog(0. All those mlog(0,...) will be replaced with trace events later.
