Not so great :/

We have some dlm fixes in our git tree which haven't made their way to Linus
yet (I wanted to run a few more tests). Would you be interested in patching
with them so we can see which bugs are left? The easiest way to get this is
to pull them out of 2.6.16-rc3-mm1:

You'll also pull a performance fix in that patch. Of course, even easier
might be to just run 2.6.16-rc3-mm1 for now as it also contains the
checkpoint list split backout.

Could you load up debugfs.ocfs2 against your file system and run the
following command:

debugfs: locate <M0000000000000000d4a94b05ae097f>

It will tell me the path to the file which that metadata lock refers to.
The path may help us figure out what sort of access we're having problems on
