struct filesystem_type (2)

• VFS provides convenience functions for filesystem_type operations:

• • get_sb_bdev() - fill superblock for block device-based filesystems
  • get_sb_nodev() - for non-physical filesystems
  • get_sb_single() - for filesystems with single instance
  • kill_block_super() - unmounts block-device based filesystem
  • kill_litter_super()/kill_anon_super() - unmounts non-physical filesystems
