Title: mount of compressed erofs shows corrupted data Status in linux-signed-hwe-6.2 package in Ubuntu: New Bug description: In some cases, file contents are corrupted if I mount a lz4 compressed erofs image file. How to reproduce: 1. Download the attached file (pip-22.0.2-py3-none-any.whl). Actually, this file is installed from python3.10-venv package and is originally located at /usr/share/python-wheels/pip-22.0.2-py3-none-any.whl. 2. `mkdir source && mv pip-22.0.2-py3-none-any.whl source/` 3. `mkfs.erofs uncomp.erofs source/` 4. `mkfs.erofs -z lz4 comp.erofs source/` 5. `mkdir mount_uncomp && mount uncomp.erofs mount_uncomp/` 6. `mkdir mount_comp && mount comp.erofs mount_comp/` 7. compare the hashes of the file for each mountpoint. If I run the above code, I found the result - md5sum source/pip-22.0.2-py3-none-any.whl : 5a1376d56e14bd0127f47e0d6a042479 - md5sum mount_uncomp/pip-22.0.2-py3-none-any.whl : 5a1376d56e14bd0127f47e0d6a042479 - md5sum mount_comp/pip-22.0.2-py3-none-any.whl : 8e01bd5ea2108f41684ba724f6d15101 And the diff of their hexdump shows 4 bytes mismatch.
