The patch titled

has been removed from the -mm tree. Its filename was

This patch was dropped because it was folded into mm-fs-prepare-for-non-page-entries-in-page-cache-radix-trees.patch

From: Johannes Weiner <hannes@xxxxxxxxxxx>
Subject: mm + fs: prepare for non-page entries in page cache radix trees fix
__pagevec_lookup() stores exceptional entries in the pagevec. They must
be pruned before passing the pagevec along to pagevec_release() or the
kernel crashes when these non-page pointers reach the page allocator.
Add a missing pagevec_remove_exceptionals() in the truncate path.
