One of the configurations supported in our specialized distribution is using
floppy to store configuration information (and live cd for everything else).
The floppy is mounted with '-o sync' so that if floppy is removed the files
are still updated. The floppy is formatted with ext2 filesystem.

This broke somewhere between 2.6.30 and 2.6.31-rc1, and was caught by our
release regression system (with VMware pseudo-floppys) but it is easily
reproducible with real hardware.

The following sequence demonstrates this:

# mount /dev/fd0 /mnt -o sync,noatime,noexec,nosuid 
# cp /etc/motd /mnt/motd.$$

(Manually eject floppy)

# umount /mnt

(I/O errors occur)

With -o sync, all I/O should have been completed when the copy was done.

This may also effect people using -o sync on USB thumb drives as well.

I tried the obvious bisection, but git bisect seems to wonder off into the
weeds now. There is no reason that bisecting between v2.6.30 and v2.6.31-rc1
should go off into v2.6.30-rc2

AFAIK that can happen if some branch was merged after 2.6.30 that happened 
to be based on a commit from v2.6.30-rc2. Did you check in what branch you 
were when that happened?

If you look at 'gitk v2.6.30..v2.6.31-rc1' and scroll to the bottom, you 
will see quite a few merges of branches that were based on commits from 
(early) v2.6.30-rcX releases.

Cheers.

That makes sense but is confusing.

Okay the scenario is:
1. Mount floppy with ext2 filesystem in sync mode
2. Write to floppy
3. Prematurely eject floppy
4. Unmount floppy

This triggers this warning in 2.6.31 which did not occur in 2.6.30

Bisecting between 2.6.30 and 2.6.31-rc1 reduced it down to:

commit 8f184f27300f66f6dcc8296c2dae7a1fbe8429c9
Author: Frederic Weisbecker <fweisbec@gmail.com>

    tracing/stat: replace linked list by an rbtree for sorting
    
    When the stat tracing framework prepares the entries from a tracer
    to output them to the user, it starts by computing a linear sort
    through a linked list to give the entries ordered by relevance
    to the user.
    
    This is quite ugly and causes a small latency when we begin to
    read the file.
    
    This patch changes that by turning the linked list into a red-black
    tree. Athough the whole iteration using the start and next tracer
    callbacks while opening the file remain the same, it is now much
    more fast and scalable.
    
    The rbtree guarantees O(log(n)) insertions whereas a linked
    list with linear sorting brought us a O(n) despair. Now the
    (visible) latency has disapeared.
    
    [ Impact: kill the latency while starting to read a stat tracer file ]

Which seems totally out of the path related to this, and no tracing is being done!

I assume that by "prematurely eject", you mean that you waited until
the activity LED had turned off, then hit the button without typing
umount?


Really, I think ext2 is just wrong here.  At unmount time it runs
ext2_sync_super(), which updates a few fields in the superblock and
tries to write them back.

But if the fs was mounted with `-osync' then the driver should be
operating synchronously, dammit!  That means that any time any syscall
alters the filesystem's s_free_blocks_count, s_free_inodes_count or
s_wtime, the driver should write those fields back to the superblock
prior to returning from the syscall.

However that might be unreasonaly anal of us, because those fields
aren't terribly important.  A fsck will whine and fix them up.

hm, I wonder why that changed.  The warning's been there for a while.

	void mark_buffer_dirty(struct buffer_head *bh)
	{
		WARN_ON_ONCE(!buffer_uptodate(bh));

that's expected, I expect.  And it's just a WARN_ON_ONCE() so it
won't be flooding logs.  We could just delete it I suppose.

yes. no activity, but not unmounted

Agreed, but it looks like it has always done that.

* [PATCH] ext2: clear uptodate flag on super block I/O error

This fixes a WARN backtrace in mark_buffer_dirty() that occurs during
unmount when a USB or floppy device is removed. I reported this a kernel
regression, but looks like it might have been there for longer
than that.

The super block update from a previous operation has marked the buffer
as in error, and the flag has to be cleared before doing the update.
(Similar code already exists in ext4).

I think the real fix is to avoid clearing uptodate in case of io errors.
For read io errors, the buffer/page should not have been uptodate to
start with, and for write io errors, an error writing back the buffer
does not mean it is somehow no longer the most uptodate copy of the data.

Higher level policy about IO errors (whether to retry, ignore, throw
out the data, etc) would be nice to implement properly too, but that is
not really the job of the low level cache and IO routines.

I proposed some patches a while back but didn't get much interest.
Maybe I should just ask someone to merge them.

I am interested in fixing current releases. But I agree it should be handled
in a general way in future.

The trace stat thing is only used for workqueue profiling,
functions profiling, branch profiling:

CONFIG_WORKQUEUE_TRACER
CONFIG_FUNCTION_PROFILER
CONFIG_PROFILE_ANNOTATED_BRANCHES
CONFIG_PROFILE_ALL_BRANCHES


And none of them seem enabled in your config.
