RFS File System data.
| uint32_t _rtems_rfs_file_system::bad_blocks |
Bad block blocks. This is a table of blocks that have been found to be bad.
| size_t _rtems_rfs_file_system::block_map_doubly_blocks |
Block map double indirect count. This is the block number per block squared and multiplied by the slots in the inode. It is the maximum number of blocks a map (file/directory) can have.
| size_t _rtems_rfs_file_system::block_map_singly_blocks |
Block map single indirect count. This is the block number per block multiplied but the slots in the inode.
| size_t _rtems_rfs_file_system::block_size |
The size of a block. This must be a multiple of the disk's media block size.
| size_t _rtems_rfs_file_system::blocks |
The number of blocks in the disk. The size of the disk is the number of blocks by the block size. This should be within a block size of the size returned by the media driver.
| size_t _rtems_rfs_file_system::blocks_per_block |
Number of block numbers in a block.
| rtems_chain_control _rtems_rfs_file_system::buffers |
List of buffers attached to buffer handles. Allows sharing.
| uint32_t _rtems_rfs_file_system::buffers_count |
Number of buffers held on the buffers list.
| int _rtems_rfs_file_system::device |
The file descriptor for device I/O.
| rtems_chain_control _rtems_rfs_file_system::file_shares |
List of open shared file node data. The shared node data such as the inode and block map allows a single file to be open more than once.
| uint32_t _rtems_rfs_file_system::flags |
Flags to control the file system. Some can be controlled via the ioctl.
| size_t _rtems_rfs_file_system::group_blocks |
Number of blocks in a group.
| int _rtems_rfs_file_system::group_count |
Number of groups.
| size_t _rtems_rfs_file_system::group_inodes |
Number of inodes in a group.
| rtems_rfs_group* _rtems_rfs_file_system::groups |
A disk is broken down into a series of groups.
| uint32_t _rtems_rfs_file_system::inodes |
Inode count.
| size_t _rtems_rfs_file_system::inodes_per_block |
Number of inodes in each block.
| uint32_t _rtems_rfs_file_system::max_held_buffers |
Number of buffers held before releasing back to the cache.
| uint32_t _rtems_rfs_file_system::max_name_length |
Maximum length of names supported by this file system.
| rtems_chain_control _rtems_rfs_file_system::release |
List of buffers that need to be released when the processing of a file system request has completed.
| uint32_t _rtems_rfs_file_system::release_count |
Number of buffers held on the release list.
| rtems_chain_control _rtems_rfs_file_system::release_modified |
List of buffers that need to be released modified when the processing of a file system request has completed.
| uint32_t _rtems_rfs_file_system::release_modified_count |
Number of buffers held on the release modified list.
| size_t _rtems_rfs_file_system::size |
The number of blocks in the file system.
| void* _rtems_rfs_file_system::user |
Pointer to user data supplied when opening.
