I thought I explained last time that you can do this with
invalidate_mapping_pages() / invalidate_inode_pages2_range() ?
Then you don't need to introduce invalidate_inode_pages().

void super_drop_pagecache(struct super_block *sb,
int (*invalidate)(struct address_space *, pgoff_t, pgoff_t))

invalidate(inode->i_mapping, 0, -1)
... then all the changes to mm/truncate.c and filemap.h go away.
