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