OK, I see your patch is like mine due to changes in linux-next (here:
I checked with next-20110721):

commit cbc4facd43b3502f644d7f01a9a48f8bec5f3e57
"fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlers"

Is it possible to have a clean...

1. OverlayFS v11 against Linux-3.0
2. OverlayFS v11 against vfs-2.6.git#for-next (see [2])
