doxygen: add prefix for groups (#9991)

2025-02-15T04:15:19Z

* 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 * 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 --------- Signed-off-by: Chen Wang

feat: add support for dfs remount functionality

2025-01-06T11:34:16Z

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.
