The patch titled
page migration cleanup: remove useless definitions
has been removed from the -mm tree. Its filename is
page-migration-cleanup-remove-useless-definitions.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: page migration cleanup: remove useless definitions
From: Christoph Lameter <clameter@xxxxxxx>
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.
