Hi Joe

Could you please try this patch 
http://people.redhat.com/agk/patches/linux/editing/dm-bufio-submit-writes-outside-lock.patch
and test if it generates some regressions for dm-thin?

Run some benchmark that you normally use for dm-thin and test if it is 
better, same or worse with the patch.

The patch changes dm-bufio so that it drops the lock when submitting bios 
inside dm_bufio_write_dirty_buffers so that there is more parallelism.
