bfs inodes

The inode contains all the information about a file except its name. Filenames are kept in the root directory, the only directory in the bfs filesystem. An inode is 64 bytes long. The number of inodes is defined when mkfs is used to create the filesystem. An inode contains the following:

• inode number (by convention, this field is set to zero to show that the inode is available)

• first data block

• last data block

• disk offset to the end-of-file (in bytes)

• file attributes

• type and mode of the file

• user ID of the owner of the file

• group ID to which the file belongs

• number of hard links to the file

• date and time the file was last accessed

• date and time the file was last modified

• date and time the file was created
