The patch titled
     Subject: lib/test-string_helpers.c: add string_get_size() tests
has been removed from the -mm tree.  Its filename was

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Vitaly Kuznetsov <vkuznets@xxxxxxxxxx>
Subject: lib/test-string_helpers.c: add string_get_size() tests

Add a couple of simple tests for string_get_size().  The last one will
hang the kernel without the 'lib/string_helpers.c: fix infinite loop in
string_get_size()' fix.
