The patch titled

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Jan Kara <jack@xxxxxxx>
Subject: mm: add variant of pagevec_lookup_range_tag() taking number of pages
Currently pagevec_lookup_range_tag() takes number of pages to look up but
most users don't need this. Create a new function
pagevec_lookup_range_nr_tag() that takes maximum number of pages to lookup
for Ceph which wants this functionality so that we can drop nr_pages
argument from pagevec_lookup_range_tag().
