Inodes

• We're going to look at this in detail because it's so interesting:

      struct inode {
        ...
        struct list_head        i_dirty_buffers;

• This is the file's buffer cache

  • When you fsync a file, i_dirty_buffers is the list of buffers that are flushed

        unsigned long           i_ino;

• This is the i-number for the inode---it's not stored on the disk, of course

        umode_t                 i_mode;

• This contains the permissions and the file type (symlink, directory, etc.)

        nlink_t                 i_nlink;

• This is the link count
