Hi Wu,

if you're queueing up writeback changes can you look into splitting
inode_wb_list_lock as it was done in earlier versions of the inode
scalability patches? Especially if we don't get the I/O less
balance_dirty_pages in ASAP it'll at least allows us to scale the
busy waiting for the list manipulationes to one CPU per BDI.
