If an + * operation is going to mark an inode dirty, it has to allocate budget for + * this. It cannot just mark it dirty because there is no guarantee there will + * be enough flash space to write the inode back later. This means UBIFS has + * to have full control over inode "clean <-> dirty" transitions (and pages + * actually). But unfortunately, VFS marks inodes dirty in many places, and it + * does not ask the file-system if it is allowed to do so (there is a notifier, + * but it is not enough), i.e., there is no mechanism to synchronize with this. + * So UBIFS has its own inode dirty flag and its own mutex to serialize + * "clean <-> dirty" transitions. + * + * The @synced_i_size field is used to make sure we never write pages which are + * beyond last synchronized inode size. See 'ubifs_writepage()' for more + * information. + * + * The @ui_size is a "shadow" variable for @inode->i_size and UBIFS uses + * @ui_size instead of @inode->i_size. The reason for this is that UBIFS cannot + * make sure @inode->i_size is always changed under @ui_mutex, because it + * cannot call 'vmtruncate()' with @ui_mutex locked, because it would deadlock + * with 'ubifs_writepage()' (see file.c).
