[PATCH v3 0/4] erofs-utils: mkfs: introduce multi-threaded compression

[Noboru Asai]

> - remove inter-file compression support from this patchset

Do you have any problems about inter-file compression functionarity?
Or make steps (split this functionarity as separate patch set)?
I'm testing v1 patch set and I have no problem like making wrong images for now.
(I couldn't apply v2 patch set without rejects.)
