- This is a heavily modified version of susfs v1.5.12
- It does not comply with the upstream offical susfs v1.5.12
- sus_mount functionality still remain in v1.5.5 as backporting it to the latest version will result a mount detection leak in some apps/detectors
- Increase susfs_open_redirect UID limit to <11000
- susfs magic mount support is still implemented and enabled
- sus_map is implemented and complied with the upstream v1.5.12 codebase
This commit requires a bunch of backports commits from v4.19 and v5.x to make sus_map working:
