      driver model: convert devices to use kobjects and sysfs. · 77057f5a
      Patrick Mochel authored
      - Define a device subsystem and register it on startup. 
      - Fill it in with fields converted from driverfs-style fields.
      - Convert device_{create,remove}_file() to create files in sysfs. 
      - Add default device attributes to device subsystem.
      - Make sure devices get proper kobject familial pointers and that the kobjects
        are registered.

      kobjects: add array of default attributes to subsystems, and create on registration. · c3f575f0
      Patrick Mochel authored
      struct subsystem may now contain a pointer to a NULL-terminated array of 
      default attributes to be exported when an object is registered with the subsystem.
      kobject registration will check the return values of the directory creation and 
      the creation of each file, and handle it appropriately. 
      
      The documentation has also been updated.

      sysfs: kill struct sysfs_dir. · 332ad69d
      Patrick Mochel authored
      Previously, sysfs read() and write() calls looked for sysfs_ops in the struct 
      sysfs_dir, in the kobject. Since objects belong to a subsystem, and is a member
      of a group of like devices, the sysfs_ops have been moved to struct subsystem,
      and are referenced from there.
      
      The only remaining member of struct sysfs_dir is the dentry of the object's 
      directory. That is moved out of the dir struct and directly into struct kobject.
      That saves us 4 bytes/object.
      
      All of the sysfs functions that referenced the struct have been changed to just
      reference the dentry.

      Introduce struct subsystem. · a6c066de
      Patrick Mochel authored
      A struct subsystem is basically a collection of objects of a certain type,
      and some callbacks to operate on objects of that type. 
      
      subsystems contain embedded kobjects themselves, and have a similar set of 
      library routines that kobjects do, which are mostly just wrappers for the
      correlating kobject routines. 
      
      kobjects are inserted in depth-first order into their subsystem's list of 
      objects. Orphan kobjects are also given foster parents that point to their
      subsystem. This provides a bit more rigidity in the hierarchy, and disallows
      any orphan kobjects.
      
      When an object is unregistered, it is removed from its subsystem's list. When
      the objects' refcount hits 0, the subsystem's ->release() callback is called. 
      
      Documentation describing the objects and the interfaces has also been added.

      [PATCH] loop breakage fix · 96c17710
      Alexander Viro authored
      Got it.  Breakage happened when Jens was switching to partial
      completions - !uptodate is not quite the same as !err ;-)
      
      With this fixed everything seems to work nicely.
