Developed CephFS case sensitivity detection and reporting for the redox-os/samba repository, enabling more accurate cross-platform file system behavior. The work involved reading the ceph.dir.casesensitive extended attribute to determine case sensitivity, then caching this capability to reduce redundant attribute reads and improve performance. Results were exposed through statvfs FsCapabilities, allowing client systems to reliably detect and adapt to CephFS case sensitivity. This feature addressed interoperability issues in environments where file system semantics differ, laying the foundation for broader CephFS capability exposure. The implementation was completed in C, leveraging expertise in VFS module development, extended attributes, and file system integration.
