From e7340f73307abed9283d0a07570d06e228c205dd Mon Sep 17 00:00:00 2001 From: Christoph Lameter Date: Fri, 23 Jun 2006 02:03:29 -0700 Subject: [PATCH] [PATCH] page migration cleanup: remove useless definitions Remove the export for migrate_page_remove_references() and migrate_page_copy() that are unlikely to be used directly by filesystems implementing migration. The export was useful when buffer_migrate_page() lived in fs/buffer.c but it has now been moved to migrate.c in the migration reorg.
