UBIFS fast path in write_begin may mark a page up to date and then discover that there may not be enough space to do the write, and so fall back to a slow path. The slow path tries harder, but may still find no space - leaving the page marked up to date, when it is not. This patch ensures that the page is marked not up to date in that case. The bug that this patch fixes becomes evident when the write is into a hole (sparse file) or is at the end of the file and a subsequent read is off the end of the file. In both cases, the file system should return zeros but was instead returning the page that had not been written because the file system was out of space.
