[RFC PATCH 0/2] erofs-utils: compression inline feature

[Yue Hu <huyue2@yulong.com>]

Now, we only support tail-end inline data for uncompressed file. We should
also support it for compressed file to decrease tail extent I/O and save
save more space. That is original intention from Xiang.

Note that, current mapping logic code in erofsuse is only based on
non-bigpcluster in erofsfuse, but i would like to present it. May refine
it for big pcluster later. Let's foucs on this on-disk improvement first.

Thanks.
