Jan Kara dff2a7b330 jdb2: Don't refuse invalidation of already invalidated buffers ... [ Upstream commit bd159398a2 ] When invalidating buffers under the partial tail page, jbd2_journal_invalidate_folio() returns -EBUSY if the buffer is part of the committing transaction as we cannot safely modify buffer state. However if the buffer is already invalidated (due to previous invalidation attempts from ext4_wait_for_tail_page_commit()), there's nothing to do and there's no point in returning -EBUSY. This fixes occasional warnings from ext4_journalled_invalidate_folio() triggered by generic/051 fstest when blocksize < pagesize.
