- Introduced `FuseInitNegotiated` structure to manage negotiated parameters during FUSE initialization. - Implemented `on_umount` method to handle unmounting, ensuring in-flight requests are properly failed and queued for destruction. - Added `queue_forget` method to send FORGET messages for node lookups. - Enhanced read request handling to enforce minimum buffer size requirements. - Updated protocol definitions to include new FUSE opcodes and flags. - Removed obsolete `fuse_test_simplefs.h` header file. Signed-off-by: longjin <longjin@DragonOS.org>
- Added a detailed phased implementation plan for DragonOS FUSE, outlining key objectives and milestones from protocol enhancements to ecosystem compatibility. - Introduced a demo application (`fuse3_demo`) based on `libfuse3`, including automatic library download and build processes. - Implemented a test application (`test_fuse3_demo`) for regression testing of the FUSE functionality. - Enhanced FUSE connection management with new opcodes and improved request handling. - Updated protocol definitions to support additional FUSE operations and flags.

- 将FUSE私有数据相关结构体移至独立模块 - 统一使用枚举类型FuseFilePrivateData表示所有FUSE文件类型 - 简化代码结构，提高可维护性 Signed-off-by: longjin <longjin@DragonOS.org>
- Introduced `FuseRequestCred` struct to encapsulate user credentials for FUSE requests. - Refactored request building and handling methods to improve code clarity and reduce redundancy. - Updated `FuseDevPrivateData` to provide a safer way to obtain a reference to `FuseConn`. - Simplified connection reference retrieval in `LockedFuseDevInode` implementations. Signed-off-by: longjin <longjin@DragonOS.org>
- Added non-blocking and blocking methods for popping pending requests in `FuseConn`. - Introduced alignment for directory entry records in `FuseNode` to ensure proper memory alignment. - Implemented methods for parsing directory entries in `FuseNode`, improving the handling of readdir and readdirplus payloads. - Added a new script `run_all_test_fuse.sh` for executing and summarizing test results for FUSE applications. Signed-off-by: longjin <longjin@DragonOS.org>
…sing - Introduced a new `wait_with_recheck` function to streamline the waiting mechanism for requests in `FuseConn`, reducing code duplication. - Refactored the `wait_complete`, `wait_initialized`, and `pop_pending_blocking` methods to utilize the new waiting function. - Added utility methods in `FuseFS` for parsing optional integer and boolean values from strings, improving the clarity of mount option handling.
