[BUG]erofs-utils v1.8.6 causes Android to fail to boot or other failures

[HassanMirza01]

with new release v1.8.6-250522, there is issue with mtk devices where Camera app dont work after repacking, not sure if unpacking gave issue which eventually shown in repack but seems like vendor/odm erofs img has issues.

Reverted to previous release and camera working fine with same files repack. i hope you can revert commits which are linked to that.

Some users reported this problem(Some users are unable to boot.). After checking, it was found that the files/permissions/selabel were consistent before and after packaging.

try: v1.8.9-250627
If the latest update does not resolve the issue, please go here:
@Kyuofox provided a solution to your problem. You can check the dev-test branch

Because it is difficult to get logs (dmesg/logcat) when the system cannot boot, we don't know what went wrong.

erofs-utils: lib: optimize space allocation

After comparison, I found that the mirrored blocks were 1 less.
Temporarily revert these...

dont have device on which i can test it, i own snapdragon and even bugged binary was able to be booted on it, it was issue on mtk for me and only for camera in that.

This bug occurs randomly and has nothing to do with MTK.

well, i told what i experienced, mtk do many things differently, so may be they doing something strictly which snapdragon not?

It may be that some files in the rom just triggered this bug, which has nothing to do with the platform.

After testing, the problem was solved (revert6).
This indicates a problem with the upstream code.
Since it is not possible to obtain valid date (logcat/dmesg), it is not possible to report to the authorities.
