    [patch 3/4] fat: dont call notify_change · b1da47e2
    Miklos Szeredi authored
    The FAT_IOCTL_SET_ATTRIBUTES ioctl() calls notify_change() to change
    the file mode before changing the inode attributes.  Replace with
    explicit calls to security_inode_setattr(), fat_setattr() and
    fsnotify_change().
    
    This is equivalent to the original.  The reason it is needed, is that
    later in the series we move the immutable check into notify_change().
    That would break the FAT_IOCTL_SET_ATTRIBUTES ioctl, as it needs to
    perform the mode change regardless of the immutability of the file.
    
    [Fix error if fat is built as a module.  Thanks to OGAWA Hirofumi for
    noticing.]
