ocfs2: Remove mlog(0) from fs/ocfs2/alloc.c
This is the first try of replacing debug mlog(0,...) to trace events. Wengang has did some work in his original patch http://oss.oracle.com/pipermail/ocfs2-devel/2009-November/005513.html But he didn't finished it. So this patch removes all mlog(0,...) from alloc.c and adds the corresponding trace events. Different mlogs have different solutions. 1. Some are replaced with trace event directly. 2. Some are replaced and some new parameters are added since I think we need to know the btree owner in that case. 3. Some are combined into one trace events. 4. Some redundant mlogs are removed. What's more, it defines some event classes so that we can use them later. Cc: Wengang Wang <wen.gang.wang@oracle.com> Signed-off-by: Tao Ma <boyu.mt@taobao.com>
