Hi all
 I have been benchmarking on an Altix 350 4way and upon
upgrading from 2.6.12-rc3 -> rc4 Git tree-id 
eed337ef5e9ae7d62caa84b7974a11fddc7f06e0 using the sn2_defconfig
with # CONFIG_MODULES is not set, I am seeing a constant stream of
the following Oops:

Badness in xfs_page_state_convert at

We hit this internally as well with our tests.  Christoph suggested the
following:

We're trylocking now if wbc->sync_mode is WB_SYNC_NONE, so having
page_dirty set on startio isn't fatal.  It should go away with the patch
below:
