    [PATCH] remove ide_cmd_type_parser() logic · 94088a7a
    Bartlomiej Zolnierkiewicz authored
    Set ide_task_t fields (command_type, handler and prehandler) directly.
    Remove unused ide_task_t->posthandler and all ide_cmd_type_parser() logic.
    
    ide_cmd_type_parser() was meant to be used for ioctls but
    ended up checking validity of kernel generated requests (doh!).
    
    Rationale for removal:
    - it can't be used for existing ioctls (changes the way they work)
    - kernel shouldn't check validity of (root only) user-space requests
      (it can and should be done in user-space)
    - it wastes CPU cycles on going through parsers
    - it makes code harder to understand/follow
      (now info about request is localized)
