From d701485a6246486fda0ee58457b82a81562a7bc4 Mon Sep 17 00:00:00 2001 From: Tao Ma Date: Thu, 24 Feb 2011 16:22:20 +0800 Subject: ocfs2: Remove masklog ML_UPTODATE. Remove mlog(0,...) and mlog(ML_UPTODATE,...) from fs/ocfs2/uptodate.c and fs/ocfs2/buffer_head_io.c. The masklog UPTODATE is removed finally.
