2025-02-15doxygen: add prefix for groups (#9991)Chen Wang
* doxygen: add prefix for groups Add "group_" prefix to doxygen group names. This makes it easier to grep with group name later. This patch only modifies the groups defined in the pathes of INPUT of documentation/Doxyfile: INPUT = . \ ../src \ ../include \ ../components/finsh \ ../components/drivers/include/drivers \ ../components/drivers/clk \ ../components/dfs/dfs_v2/src \ ../components/dfs/dfs_v2/include Other groups are not touched. Signed-off-by: Chen Wang <[email protected]> * ci: fixed error report when run file_check.py Such as: - "please delete extra space at the end of this line." - "the RT-Thread error code should return negative value. e.g. return -RT_ERROR" Signed-off-by: Chen Wang <[email protected]> --------- Signed-off-by: Chen Wang <[email protected]>

According to the POSIX.1, we should give a EBUSY on umount(2) of busy filesystem. Signed-off-by: Shell <[email protected]>
2025-01-06feat: add support for dfs remount functionalityShell
This patch introduces a remount feature for the DFS, allowing for the modification of mount parameters without unmounting the filesystem, the remount functionality helps modify certain mount flags (like `MS_RDONLY`) without requiring an unmount, providing more control over mounted filesystems in the system. The updates is essential for user space init proc to cleanup the runtime resource, ensuring clean handling of cached data and enhancing system robustness during power down processing. Changes: - Defined new constants for remount flags in `dfs_fs.h`. - Added the `dfs_remount()` function in `dfs_fs.c` to handle remount operations. - Introduced a check for unsupported flags and handle error conditions such as invalid paths or non-directory targets. - Updated the `dfs_mnt` structure in `dfs_mnt.h` to include a read-only flag (`MNT_RDONLY`). - The `dfs_remount()` function allows changing the read-only status of a mounted filesystem. - Added `MNT_LAZY_UMNT` and `MNT_RDONLY` flags to `dfs_mnt` structure. - Introduced `dfs_mnt_setflags` function for dynamic flag management. - Updated `dfs_remount` to utilize `dfs_mnt_setflags` for flag setting. - Enhanced unmount operations with `dfs_mnt_umount_iter` and lazy unmounting. - Added `dfs_pcache_clean` to handle cache cleanup for read-only mounts. - Improved error reporting in `dfs_umount` for better user feedback. - Refactored `sys_mount` to streamline parameter handling and support remounts. - Introduced `_cp_from_usr_string` helper for user-space string operations. - Updated internal APIs to ensure consistency in reference count management.

warnings in Doxygen. 将Doxygen输入文件(由Doxyfile中的INPUT定义)中的失效Doxygen分组指令(如/*@*/和/*@}*/)更改为有效的分组指令(如/**@*/和/**@}*/);(此处只对INPUT中的文件做了修改,bsp目录下和libcpu目录下存在近万个失效的Doxygen分组指令,但由于不作为文档的输入文件且这些文件过于庞大老旧,没有对这些文件中的无效指令做修改) 将图片文件统一放入了images目录下; 修改了Doxyfile和部分Doxygen注释,使得Doxyfile能够定位到新的代码路径且不受重复实现的影响; 解决了一些注释中的参数名不匹配、参数多余/缺失等问题。
