Thanks for the patch, could you elaborate how to use this?

A detailed command line usage would be better.

(Also honestly I will try to release erofs-utils 1.9 in
  a few days for the upcoming ubuntu LTS, so I have to
  finish erofs fsmerge feature for compression layout
  after the version is released...)

Thanks,
Gao Xiang
