      fat: introduce special inode for managing the FSINFO block · 020ac5b6
      Artem Bityutskiy authored
      This is patchset makes fatfs stop using the VFS '->write_super()' method
      for writing out the FSINFO block.
      
      The final goal is to get rid of the 'sync_supers()' kernel thread.  This
      kernel thread wakes up every 5 seconds (by default) and calls
      '->write_super()' for all mounted file-systems.  And the bad thing is that
      this is done even if all the superblocks are clean.  Moreover, some
      file-systems do not even need this end they do not register the
      '->write_super()' method at all (e.g., btrfs).
      
      So 'sync_supers()' most often just generates useless wake-ups and wastes
      power.  I am trying to make all file-systems independent of
      '->write_super()' and plan to remove 'sync_supers()' and '->write_super'
      completely once there are no more users.
      
      The '->write_supers()' method is mostly used by baroque file-systems like
      hfs, udf, etc.  Modern file-systems like btrfs and xfs do not use it.
      This justifies removing this stuff from VFS completely and make every FS
      self-manage own superblock.
      
      Tested with xfstests.
      
      This patch:
      
      Preparation for further changes.  It introduces a special inode
      ('fsinfo_inode') in FAT file-system which we'll later use for managing the
      FSINFO block.  Note, this there is already one special inode ('fat_inode')
      which is used for managing the FAT tables.
      
      Introduce new 'MSDOS_FSINFO_INO' constant for this special inode.  It is
      safe to do because FAT file-system does not store inode numbers on the
      media but generates them run-time.
      
      I've also cleaned up the comment to existing 'MSDOS_ROOT_INO' constant,
      while on it.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
