Tristan Ye has done some refactoring against our truncate
process, so some functions like ocfs2_prepare_truncate and
ocfs2_free_truncate_context are no use and we'd better
remove them.

ENTRY is used to record the entry 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.
So for mlog_entry_void, we just remove it.
for mlog_entry(...), we replace it with mlog(0,...), and they
will be replace by trace event later.

From: Tao Ma <tao.ma@oracle.com>
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. So in case of report error, a
mlog_errno is used while if all the errors in the function are
properly reported, mlog_exit is just removed.
for mlog_exit:
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.

About one year ago, Wengang Wang tried some first steps
to add tracepoints to ocfs2. But at that time we don't
have ocfs2 1.6 introduced, so we delay this work until now
after ocfs2 1.6 and UEK(Unbreakable Enterprise Kernel) are
released.
Wengang's original patch is here:
http://oss.oracle.com/pipermail/ocfs2-devel/2009-November/005512.html
But as Steven Rostedt indicated in his article
http://lwn.net/Articles/383362/, we'd better have our trace
files resides in fs/ocfs2, so I rewrited the patch using the
method Steven mentioned in that article.

Let's not mention marketing terms. Just say that we had
to delay the work.

From: Tao Ma <tao.ma@oracle.com>
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 tracepoints. 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.

If you'd split the even up into classes depending on the actual meaning
of num the trace could contain a descriptive name that makes it a lot
more readable. And btw, the above would be a lot more readable if
formatted like normal kernel code:
DECLARE_EVENT_CLASS(ocfs2__int,
TP_PROTO(int num),
TP_ARGS(num),
TP_STRUCT__entry(
__field(int, num)
),
TP_fast_assign(
__entry->num = num;
),
TP_printk("%d", __entry->num)
);

FYI, if you have a lot of instances ofa given even class using a little
macro makes declaring them a lot simpler, take a look at
fs/xfs/linux-2.6/xfs_trace.h for examples.

ok, I will change it in the next round.

OK, I will look at it and use a macro. thanks.

This is the 2nd step to remove the debug info of DISK_ALLOC.
So this patch removes all mlog(0,...) from localalloc.c and adds
the corresponding tracepoints. Different mlogs have different
solutions.
1. Some are replaced with trace event directly.
2. Some are replaced while some new parameters are added.
3. Some are combined into one trace events.
4. Some redundant mlogs are removed.

From: Tao Ma <boyu.mt@taobao.com>
As there are no such debug information in fs/ocfs2/ioctl.c,
fs/ocfs2/locks.c and fs/ocfs2/sysfile.c, ML_INODE are also
removed.

ocfs2_iget is used to get/create inode. Only iget5_locked
will give us an inode = NULL. So move this check ahead of
ocfs2_read_locked_inode so that we don't need to check
inode before we read and unlock inode. This is also helpful
for trace event(see the next patch).

Oh, I suddenly found that I send an older version. So it contains some
bugs and I will update them after the review is done.
But it doesn't prevent you guys from review, and please don't run it by
now. ;)

Tao,
Overall this seems pretty straightforward. There wasn't a lot
of editing of masklog entries; we still have a million tracepoints. I
wonder how much memory that will use. Have you checked the space usage
of all the sysfs files for all of our tracepoints?
Aside from my comment about marketing terms in patch comments
(hehe), I'm OK with going forward with these patches. I would love the
ability to turn specific traces on and off.
Well, one generic comment. It seems a lot of our log messages
have gone from "ocfs2_foo(): Change blah 0x%p to new_blah 0x%p" to
"ocfs2_foo(): %p %p". I wonder if that is going to be hard to read.

Sorry, I don't know how to check the space usage of these files. any tips?

OK, I will regenerate the patches with advices from Christoph and your.

Yeah, I used to think of adding all these descriptive strings to trace
buffers, but finally I gave up. The reason is that no matter how we
print the message in the trace buffer, we have to go to read the codes
and with the codes, everything should be clear enough. ;)

Just count the number of files and directories added to sysfs.
I believe the files disappear when not open, but the directories
I think have inode and dentry structures around permanently..

OK, so
#find /sys/kernel/debug/tracing/events/ocfs2 -type d|wc -l
give me 319. Every trace event dir has 4 members(enable,filter,format
and id). So it contains about 1600(dir+files).

That's a lot. ext4 currently has < 40.
I am wondering whether it is wise to treat this as a mlog replacement.
One suggestion would be to not remove all mlogs (other than remove _enter
and _exit as they are completely useless). Add trace events one by one. Coarse
tracing like ext4 has. Remove only those mlogs.

I think what matters to count is dirs, because files disappear
when you're not using them.
If you have 319 trace event directories, that's 319 inodes. On
my x86, a vanilla struct inode is 360 bytes and a dentry is 136 bytes.
That's 154K always in RAM for these knobs. I gotta say that I'm not too
worried about 154K. On x86_64 (ca-build24) this grows to 241K. I
imagine it will double when cluster and dlm are moved to similar trace
events.
Are we OK with 300K on x86 and 500K on x86_64 always used up by
these tracing entries?

I'm ok with that.

yeah, it isn't much I guess.
And for ext4, yes, it has a small number because they have a very
limited debug tracing than us, maybe because they evolved from
ext2->ext3->ext4. So the code base is really stable now. And I guess we
can remove some of the trace events if we feel that the code is stable
enough. ;)

Tao

I really don't like the way this is split into tons of patches, which
makes reviewing what's going on pretty hard. In addition to the
preparatiory patch just one patch is more than enough, or if you really
want two: one to remove the old mlog code and one to add the trace
events.

I have to say, I would have found a single massive patch really
painful to read. The eye glazes over so many repetitive changes. But
I've now read it, and we can certainly push it upstream as one commit if
you like.

It doesn't matter too much - in the end it's mostly you guys who have to
deal with it.

Hi Joel,
any plan to integrate this patch set for the next merge window?
