Hi Greg,
There are two erofs bugfix & cleanup patches ready for staging-next upstream.
The original preview thread:
  https://lists.ozlabs.org/pipermail/linux-erofs/2018-July/000281.html
  https://lists.ozlabs.org/pipermail/linux-erofs/2018-August/000294.html 

With regard to linux-next conflicts, there are also patches to solve them.
Chao will send them in batch to Stephen later.

Thanks,
Gao Xiang
