Hi all,

This patchset is based on the original patch
https://lore.kernel.org/r/20190818135923.27444-1-blucerlee@gmail.com
and several fixes / compression support by Huang Jianan
https://lore.kernel.org/r/20201015133959.61007-1-huangjianan@oppo.com

with my additional 9 incremental patches to refactor my current
development status, which will be folded into original patches
in the next WIP version since the fuse approach hasn't been
merged into dev branch yet.

To summarize the benefits of erofsfuse, I think it would be:

 - erofs images can be supported on various platforms;
 - an independent unpack tool can be developed based on this;
 - new on-disk feature can be iterated, verified effectively.

Any feedback or/and follow-on development/cleanup is welcomed.
(we still have a lot to do for the entire erofsfuse codebase...)

Thanks,
Gao Xiang
