Josef Bacik e5ad49e215 btrfs: add a trace class for dumping the current ENOSPC state ... Often when I'm debugging ENOSPC related issues I have to resort to printing the entire ENOSPC state with trace_printk() in different spots. This gets pretty annoying, so add a trace state that does this for us. Then add a trace point at the end of preemptive flushing so you can see the state of the space_info when we decide to exit preemptive flushing. This helped me figure out we weren't kicking in the preemptive flushing soon enough.
