Hi Chengguang,
Good question! It's in the final stage of preparation to open source erofs-mkfs (actually they are now struggle at how to properly spilt
into reasonable patches this week), hopefully the implementation could be released at the next week. (sorry I didn't mean to delay,
I have to put it in the first place --- successfully launch our linux-erofs products to the market)
@Guifu Li <[email protected]> is the original author of erofs-mkfs, he will post the original mkfs source code to linux-erofs mailing list
and he will maintain erofs-mkfs together with @Wei Fang <[email protected]> later. You can contact them for further informations.
--- these piece of code is actually not clean enough (a lot hacked/dirty code compared to the kernel code) so a lot of cleanup will be done then.
currently, you can get erofs-mkfs binary from (still sorry to say that...):
https://github.com/hsiangkao/erofs_mkfs_binary
erofs is now in productization for these months, if all things go well, you'll see that HUAWEI mobile phones on the market run in erofs in few months. :)
These months I'm busy in solving bugs found by internal beta users and tuning memory policy in heavy memory workload for the best performance compared to ext4
(we have native in-place decompression compared with squashfs/btrfs, thus less extra memory allocation results in lower memory memory reclaim / page-writeback
for devices with limited memory, see: https://lists.ozlabs.org/pipermail/linux-erofs/2018-August/000494.html) in order to gain the competitive user experience
comparing to uncompressed filesystem solutions. I will update a document to describe our core design and linux-erofs future roadmap in this linux-4.21 round.
Thanks,
Gao Xiang

Hi Xiang,
Thanks for your detail explanations!
