As an update to this thread, we brought up this issue at LSF/MM, and
there is a thought that we should be able to solve this problem by
having lock_buffer() check to see if the buffer is locked due to a
write being queued, to have the priority of the write bumped up in the
write queues to resolve
Add buffer_head flags so that buffer cache writebacks can be marked
with the the appropriate request flags, so that metadata blocks can be
marked appropriately in blktrace.

This allows metadata writebacks which are issued via block device

As Dave Chinner pointed out at the 2013 LSF/MM workshop, it's
important that metadata I/O requests are marked as such to avoid
priority inversions caused by I/O bandwidth throttling.
