See my latest comment here:

    https://bugzilla.kernel.org/show_bug.cgi?id=17361#c14

This subject line is highly misleading, since after -rc4, the stack
traces are in places all over the kernel, in other places other than
ext4/jbd2.  So I fear no one is looking at this bug report given the
highly misleading subject line.

It looks like you have spinlock debugging, and yet there wan't any
spinlocks listed on the initial ext4 might_sleep() warning.  So
something looks highly confused.

The fact that you closed other bugs as duplicates of this one that
relate to kmemcheck makes me wonder if this is really a kmemcheck bug.
(If so, the subject line here is doubly, doubly misleading.)

Do you see any symptoms if you turn off kmemcheck?  Are you sure this
isn't just only a kmemcheck bug?

I just had a quick glance at the report, and here's my gut feeling: I
see perf symbols in the stack trace. I don't think kmemcheck and perf
play nicely together (for example if perf uses NMIs to write data to
its buffers, it could get a page fault inside the NMI handler, which
is not so nice, I think).

Isn't this exactly what Frederic Weisbecker tried to detect and warn
about in a patch that I saw recently?

Please do as Ted suggested and try to turn kmemcheck off.

Note: I'm seeing this warning (Dirtiable inode bdi default != sb bdi)
when I moved from 2.6.36-rc3 to 2.6.36-rc6, using ext4 as a root
partition, and running mke2fs and e2fsck on ext2, ext3, and ext4 file
systems.  So I'm seeing this as a known regression from rc3 to rc6.
Maybe it's different bug with ext4, but in any case, it's highly
annoying.

Thanks for the info.  I wonder who should see this report.

Andrew, do you know whose area that is?

Oops, correction, the correct warning that I'm seeing is:

Jan, any chance this is caused by the recent bdi change?

  Yes, it's caused by one of my fixes. It's harmless (the warning I've
added is just too strict). Christoph has a patch that also fixes this
- http://lkml.org/lkml/2010/9/29/76. I hope he'll push it soon.

I've not been able to reproduce it yet with 2.6.36-rc7, but there's
been no known recent bugfix in this area so whether the bug is fixed
or not is unknown.  If I've not been able to reproduce it on -rc7 or
-rc8 after next weekend we could close the bug.

OK, please close the bug when you think it's time or let me know if you can't
close it yourself.
