Subject: [PATCH 12/12] nilfs2: Convert metadata aops from writepage to writepages
From: "Matthew Wilcox (Oracle)" <willy@...radead.org>
By implementing ->writepages instead of ->writepage, we remove a
layer of indirect function calls from the writeback path and the
last use of struct page in nilfs2.
[ konishi.ryusuke: fixed panic by using buffer_migrate_folio_norefs ]
